Tunnel Falls is a 12-qubit silicon-based chip developed by Intel. It is the company’s first silicon spin qubit device released to the research community in June 2023. The chip is fabricated on 300-millimeter wafers in the D1 fabrication facility, and leverages Intel’s most advanced transistor industrial fabrication capabilities.
Silicon spin qubits are up to 1 million times smaller than other qubit types. The Tunnel Falls chip measures approximately 50nm x 50nm, potentially allowing for faster scaling. These 12-dot chips can form between four to 12 qubits that can be isolated and used in operations simultaneously depending on how the researchers operates its systems. The company plans to continue to improve the performance of the chip and integrate it into its full quantum stack with the Intel Quantum Software Development Kit (SDK). [1] [2]
However, it is important to note that silicon spin qubits are still in their early stages of development. It is possible that another technology, such as superconducting qubits, will eventually become the dominant technology for quantum computing. Only time will tell which technology will ultimately prevail.

Basic principles of quantum computing
Quantum computing is a type of computing that uses the principles of quantum mechanics to solve problems that are intractable for classical computers. Quantum mechanics is a branch of physics that deals with the behavior of matter and energy at the atomic and subatomic levels.
One of the key principles of quantum mechanics is superposition. In x86, a bit can be in one state or the other, 0 or 1. However, in quantum computing, a qubit can be in a superposition of both states at the same time. This means that a quantum computer can perform calculations on all possible combinations of bits at the same time, which gives it a massive speed advantage over classical computers.
Another key principle of quantum mechanics is entanglement. Entanglement is a phenomenon where two or more particles are linked together in such a way that they share the same fate, even if they are separated by a large distance. This allows quantum computers to share information between different parts of the computer, which can further speed up calculations.
How it differs from x86
Quantum computers differ from classical computers in a number of ways. Here are some of the key differences:
Quantum computers use qubits instead of bits. A qubit is a quantum bit, which is the basic unit of information in quantum computing. Unlike a classical bit, which can only be in one of two states, a qubit can be in a superposition of both states at the same time. This means that a qubit can represent an exponentially larger number of values than a classical bit, which gives quantum computers a huge potential advantage for certain types of problems.
The ability of qubits to operate in multiple states is what makes them perfectly suited for high-performance computing in sectors like cybersecurity, drugs discovery, materials design and artificial intelligence.
For example, a processor with just 50 qubits would be capable of performing more calculations than there are atoms in the universe. The advantage is immense - problems that seem intractable today, like advance AI and drug development, could be solved in minutes instead of years.
Quantum computers use entanglement to share information between different parts of the computer. This allows quantum computers to perform calculations much faster than classical computers.
Some of the potential applications of quantum computing
As quantum computers continue to develop, we can expect to see them being used to solve some of the most challenging problems in cybersecurity, artificial intelligence, and other fields. Quantum computers have the potential to revolutionize a wide range of industries, including:
Cryptography: Quantum computers could be used to break the encryption algorithms that are currently used to protect sensitive data.
Drug discovery: Quantum computers could be used to simulate the behavior of molecules, which could help to accelerate the discovery of new drugs.

Financial modeling: Quantum computers could be used to model complex financial systems, which could help to improve risk management and investment strategies.
Genealogy: Quantum computers could be used to analyze DNA much more quickly and efficiently than classical computers. This could help scientists to identify genetic markers for diseases, to trace family lineages, and to better understand the evolution of human DNA.
Pharmaceutical: Quantum computers could be used to design new drugs much more quickly and efficiently than classical computers. This could help scientists to find new treatments for diseases, to develop new vaccines, and to improve the safety and efficacy of existing drugs.

The future of quantum computing
The future of quantum computing is still uncertain. However, there is a lot of excitement about the potential of this technology. If quantum computers are able to live up to their potential, they could revolutionize the way we live and work.
Potential Impact of Quantum Computing on the x86 Architecture
The x86 architecture is based on the von Neumann architecture. It was first developed by Intel in 1978 and has been used in a wide variety of computers, including personal computers, servers, and embedded systems that is still used in most modern computers. The x86 architecture has been extended over the years to add new features and capabilities. However, it has retained its basic compatibility with earlier versions of the architecture, which has allowed it to become the dominant computer architecture in the world.
The Dominant of x86 Architecture
Some of the reasons why the x86 architecture is so popular because the x86 architecture is designed to be very efficient in terms of both performance and power consumption. It is a very flexible and very well-supported by a wide range of hardware and software vendors.The x86 architecture is a very versatile and powerful architecture that is used in a wide variety of computers. It is likely to remain the dominant computer architecture for many years to come.
x86-based Systems Vulnerability
As quantum computers become more powerful, the security of x86 systems (x86 Architecture) will become increasingly vulnerable. Quantum computing has the potential to have a significant impact on the x86 architecture. One of the most important impacts is that quantum computers could be used to break the encryption algorithms that are currently used to protect x86-based systems.
The most commonly used encryption algorithms for x86-based systems are based on the RSA and Diffie-Hellman algorithms. These algorithms are based on the difficulty of factorizing large numbers. However, quantum computers could be used to factor large numbers much more quickly than classical computers. This means that quantum computers could be used to break the encryption algorithms that are currently used to protect x86-based systems.
If quantum computers are able to break the encryption algorithms that are currently used to protect x86-based systems, this could have a significant impact on the security of x86-based systems. This is because sensitive data that is currently protected by encryption could be accessed by unauthorized users. This could lead to data breaches, identity theft, and other security incidents.
Beside the widely used RSA there are ECC and AES key cryptography. ECC is a public-key cryptography algorithm that is based on the elliptic curve discrete logarithm problem. This problem is believed to be difficult to solve even for quantum computers. However, it is not impossible to solve, and there is no guarantee that ECC will be completely secure against quantum computer attack. AES is a symmetric-key cryptography algorithm that is based on the Rijndael block cipher. This cipher is believed to be very secure, and it is not clear if quantum computers will be able to break it. However, there is always the possibility that a new quantum algorithm could be developed that could break AES.
Protecting x86-based Systems
There are a number of post-quantum cryptography algorithms that have been developed that are designed to be resistant to quantum computer attack. These algorithms include CRYSTALS-Kyber, NTRUEncrypt, and SIKE. It is not clear which of these algorithms will be the most secure, but they are all a good option for protecting sensitive data in the quantum era.
Businesses and organizations can help to protect their x86-based systems from quantum computing attacks. Here are some of the steps that can be taken:
- Use post-quantum cryptography algorithms. Post-quantum cryptography algorithms are designed to be resistant to attack by quantum computers. There are a number of different post-quantum cryptography algorithms that have been developed, and it is still too early to say which algorithm will be the most secure. However, it is important to start using post-quantum cryptography algorithms as soon as possible in order to ensure that sensitive data is protected even as quantum computers become more powerful.
- Use quantum-safe hardware. Quantum-safe hardware is designed to be resistant to attack by quantum computers. This includes hardware that uses quantum-resistant encryption algorithms and hardware that is designed to be tamper-proof.
- Use quantum-safe protocols. Quantum-safe protocols are designed to be secure even in the presence of quantum computers. This includes protocols that use quantum-resistant cryptography algorithms and protocols that are designed to be resistant to quantum attacks.
- Educate employees about quantum security. Employees need to be aware of the risks of quantum computing and how to protect sensitive data. This includes training employees on how to use post-quantum cryptography algorithms, quantum-safe hardware, and quantum-safe protocols.
In addition to these steps, businesses and organizations can also take the following steps to to ensure that they are prepared for the quantum era and that they can protect their sensitive data from quantum computing attacks.:
Start research and development of quantum-safe technologies. Businesses and organizations need to start researching and developing quantum-safe technologies. This includes developing new encryption algorithms, hardware, and protocols that are designed to be resistant to quantum attack.
Start planning for the quantum workforce. Businesses and organizations need to start planning for the quantum workforce. This includes training employees on quantum security and recruiting new employees with quantum expertise.
The Future of x86
It is difficult to say for sure when quantum computers will become commercially available for anyone. However, some experts believe that it could happen within the next decade. If this is the case, it is likely that x86 systems would not become obsolete overnight. However, over time, quantum computers would become more powerful and affordable, and they would eventually replace x86 systems for many applications.
That’s why the future of x86 in the quantum era is uncertain. Some experts believe that x86 will be able to adapt to the challenges posed by quantum computing, while others believe that it will be replaced by a new architecture that is better suited for the quantum era.
Ultimately, the future of x86 in the quantum era will depend on the development of post-quantum cryptography algorithms and quantum-safe hardware. If these technologies are developed, then x86 could continue to be used in the quantum era. However, if these technologies are not developed, then x86 may need to be replaced by a new architecture that is resistant to quantum attack.
Here are some of the possible scenarios for the future of x86 in the quantum era:
X86 is adapted to use post-quantum cryptography algorithms. In this scenario, x86 would continue to be used in the quantum era, but it would need to be updated to use post-quantum cryptography algorithms. This would allow x86 to continue to provide secure computing even in the face of quantum attack.
X86 is replaced by a new architecture that is resistant to quantum attack. In this scenario, x86 would be replaced by a new architecture that is designed to be resistant to quantum attack. This new architecture would be able to provide secure computing even in the face of quantum attack.
X86 is phased out in favor of other architectures. In this scenario, x86 would be phased out in favor of other architectures that are better suited for the quantum era. These other architectures may be based on different principles than x86, and they may be able to provide better performance or security.
It is too early to say which of these scenarios will come to pass. However, it is clear that the future of x86 in the quantum era is uncertain.
However, x86 systems will still be used for some applications, such as running legacy software and handling tasks that do not require a lot of processing power.
Here are some of the applications where x86 systems might still be used:
Running legacy software: Many businesses and organizations still rely on legacy software that was not designed to run on quantum computers.
Handling tasks that do not require a lot of processing power: Some tasks, such as web browsing and email, do not require a lot of processing power and can be handled by x86 systems.
Education: Classical computing systems can still be used to teach students about computer science and programming.
Overall, it is likely that x86 systems will not become obsolete overnight. However, over time, quantum computers will become more powerful and affordable, and they will eventually replace x86 systems for many applications.
