What could quantum computing breakthrough ‘Willow’ mean for the future of Bitcoin and other cryptos

Crypto and quantum computing

The advent of quantum computing presents both opportunities and challenges for the field of cryptography, especially in relation to cryptocurrencies.

Quantum computers, leveraging the principles of quantum mechanics, have the potential to revolutionise computing by solving certain problems significantly faster than classical computers.

One of the primary concerns is the impact of quantum computing on cryptographic algorithms that underpin the security of cryptocurrencies like Bitcoin and Ethereum.

Traditional public-key cryptography, which relies on the difficulty of factoring large prime numbers or solving discrete logarithms, could be broken by a sufficiently powerful quantum computer. Algorithms such as RSA, ECC (Elliptic Curve Cryptography), and DSA (Digital Signature Algorithm) could become vulnerable, as quantum algorithms like Shor’s algorithm are capable of efficiently solving these problems.

This potential vulnerability poses a significant threat to the security and integrity of cryptocurrency transactions. If quantum computers can crack these cryptographic codes, they could potentially access private keys, allowing malicious actors to steal funds or forge transactions. As a result, the trust that underpins the entire cryptocurrency ecosystem could be eroded.

However, the quantum threat is not without its solutions. The field of post-quantum cryptography is actively developing new cryptographic algorithms that are resistant to quantum attacks.

These algorithms leverage mathematical problems believed to be hard even for quantum computers, such as lattice-based cryptography, hash-based cryptography, and multivariate polynomial cryptography.

Transitioning to post-quantum cryptographic algorithms is crucial for ensuring the long-term security of cryptocurrencies in a quantum computing era.

In conclusion, while quantum computing poses a formidable challenge to current cryptographic systems, proactive measures and the development of quantum-resistant algorithms can mitigate these risks.

The cryptocurrency industry must stay ahead of the curve, adopting new technologies and strategies to safeguard against potential quantum threats and ensure the continued security and trust in digital currencies.

It has been estimated that the arrival of quantum computer is at least 10 years away. But is that allowing for the use of AI in its creation?

What is Willow and Quantum Computing?

Willow is the start of a new era of ultra-powerful ‘quantum’ microchips designed by Google. Willow’s speed is almost incomprehensible – according to Google, it is able to perform a computation in under five minutes that would take one of today’s fastest supercomputers 10 septillion years to solve.

This new chip design will inevitably lead to new quantum innovations and computer design over the coming years.

Ten septillion is 10,000,000,000,000,000,000,000,000 years.

If you don’t understand (not many people do) what makes up quantum computing – there is a very simplified way simplified way of thinking about the breakthrough.

Imagine a maze and how a classical computer would try to find its way through the maze from start to finish. It would try one potential path at a time. A quantum computer would be able to try each path at the same time.

The quantum computer is coming. The only delay will be in design restrictions and the power needed to run the system.

Scientists create ‘world’s purest silicon’ – it has the power to change the world

Purest silcon created

Scientists have recently achieved a remarkable breakthrough by creating pure silicon, which could pave the way for quantum computing

The world’s purest silicon

Researchers have developed an ultra-pure form of silicon, known as silicon-28 (Si-28), which is fundamental for ‘silicon-spin qubits’ in quantum computers. This advancement addresses a major challenge in quantum computing: the ‘fragile quantum coherence.’

Quantum computers tend to accumulate errors quickly due to slight environmental changes, affecting their dependability.

Quantum bits, or qubits, are analogous to classical computer bits but are extremely sensitive to environmental interference.

Technical

Current quantum computers, even when cooled to near absolute zero, can only maintain error-free operation for a very short time.

This new technique generates qubits by embedding phosphorus atoms into crystals of pure, stable silicon. A concentrated silicon beam then directs onto a silicon chip, replacing impurities with pure silicon.

As a result, the impurity levels in silicon have been significantly reduced, from 4.5% to a mere 0.0002%.

David Jamieson, a project co-supervisor from the University of Melbourne, mentioned that the team achieved this level of purity using a standard piece of equipment – an ion implanter – that’s typically found in semiconductor fabrication laboratories.

Richard Curry, a professor at The University of Manchester where extensive research took place, believes that this advancement could accelerate the development of operational quantum computers. Processes that might have taken a decade to complete could now be accomplished in potentially half that time or less.

Potential impact

Practical quantum computers have the potential to revolutionize numerous fields

  • Energy Optimization: They can solve intricate problems related to energy.
  • Artificial Intelligence: Quantum computers may significantly boost AI capabilities.
  • Drug Discovery: They could expedite drug development and molecular simulations.
  • Communication: They can enhance encryption and communication protocols.

The creation of the world’s purest silicon represents a significant step forward in the development of large-scale quantum computers.
