futureQuantum Computers and Applications Over the Next 5 Years

This article has information from the quantum computer expert John Preskill. We are going to get more and better quality qubits with lower error rates. The overhead cost for error correction improves as gate error rate declines. The Google Quantum …

ibmIBM Hackathon Leads to Quantum Cloud Integration With Trapped Ion Devices

Qiskit, is IBM’s open-source quantum computing platform and it now works with trapped ion devices – not just the IBM superconducting systems. The first company to connect Qiskit to a trapped ion device is Austrian-based startup Alpine Quantum Technologies. Their …

futureMicrosoft’s Hunt for a Topological Quantum Computer Qubit

Microsoft is developing Majorana-based topological quantum computer qubits which will be higher-quality and lower error rate qubits. A high-quality hybrid system made of InSb nanowires with epitaxial-grown Al shells has revealed ballistic superconductivity and quantized zero-bias conductance peak. This holds …

futureGoogle’s Quantum Supremacy is a Foundation Where Quantum Systems Were Engineered to Solve Big Problems

The Google team forced themselves to work on the hardest part of quantum computers which is quantum systems engineering. Quantum systems engineering is making everything work together at the same time. The system maintained quantum operation for 200 seconds and …

futureQuantum Computing Progress is Way Faster Than Classical Computers

IBM says they could use 250 petabytes of memory and the best supercomputer to match a 53-qubit Google quantum computer on a particular problem. Scott Aaronson notes that this clearly shows that quantum supremacy is clearly emerging. IBM paper says …

futureIBM Disputes Google’s Quantum Supremacy Claim

Google claims their 54 qubit quantum computer can solve a problem in 200 seconds that would take a regular supercomputer 10,000 years but IBM says it would take 2.5 days or much less for a supercomputer to solve. Nextbigfuture notes …

futureWith Quantum SpeedUp Proven Will There Be Quantum Manhattan Projects?

Google will likely announce quantum speedup and quantum supremacy has been proven using the random circuit selection problem. It is pretty clear that physics allows quantum speedup. Will there be Quantum Manhattan Projects? Phase 1a – Scale existing superconducting technology …

artificial intelligenceGoogle Quantum Supremacy Problem Involved Random Number Sampling

An important milestone for quantum computers seems to have been reached with Google using a quantum computer to solve a problem 1 billion times faster than the fastest supercomputer in the world. This could be the beginning of quantum supremacy. …
