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 …

JP Morgan Research on Quantum Computing for Finance

JP Morgan is working to apply all kinds of quantum systems with all kinds of quantum hardware. They have proved different clear academic examples of speedup over classical systems with quantum systems. However, it is currently has not been done on major financially valuable problems. The proofs are done on problems which are easy to …

Quantum Supremacy Keynote at Q2B Conference 2023

I am at the Q2B (Quantum to Business) conference this week. Scott Aaronson is presenting the keynote today and talking about Quantum Supremacy. There are specific examples of speedup quadratic and polynomial speedups on specific problems. There is no general speedup proven yet. It is easier to measure the speedup on weird problems and specific …
