BREAKTHROUGH – Better Algorithms for Classical Computers to Efficiently Compete With Quantum Computers

A new algorithm can further exploit the twin challenges of information loss and translation to mimic a quantum computer with far fewer resources than previously thought. It was previously though that quantum computers with 50-100 logical low error qubits would be able to surpass regular supercomputers. New algorithms are showing that regular computers could beat …

Bitcoin Vulnerabilities in Mining, Signatures and Transactions to Quantum Computers

Quantum computers leverage some aspects of quantum physics to make computers. They can create huge amounts of quantum states but it is also difficult to make the actual algorithms to use the abundant states. A classical (regular) computer would need more atoms than are in the entire universe to match the number of quantum stats …

Worldchanging Quantum Computers Means Science and Technology Will Get Better Faster

Despite steady improvements in quantum computers, they are still noisy and error prone, which leads to questionable or wrong answers. In June, 2023, scientists predicted that Quantum Computers won’t truly outcompete todays classical supercomputers for at least five or 10 years, until researchers can adequately correct the errors that bedevil entangled quantum bits, or qubits. …

PsiQuantum Developing Megaqubit Photonic Quantum Computer

PsiQuantum has raised about $665 million and has a valuation of over $3 billion. PsiQuantum is developing a photonic quantum computer that will have millions of physical qubits and eventually millions of error corrected qubits. Their belief is that small scale quantum systems will not be useful and only large scale systems will be able …
