We have entered the start of new era of error corrected quantum computers. There has been a journal Nature paper on the work of a 48 logical qubit error corrected system by researchers from Harvard, MIT, QuEra and NIST/Maryland Usher. There is another article that gives the state of quantum error correction today. There is …
Quantum Computer science legend, Dr John Preskill, just delivered a Q2B Quantum computer 2023 keynote talk on the state of Quantum Error correction with quantum computers. Preskill reported that Rydberg Atom and movable atom approaches are making the fastest progress to quantum error correction. There is a Harvard/MIT paper being released today that describes some …
I was at the Q2B quantum Computer conference today and there was a talk about NSM-10 and the change of the encryption that underlies global finance and data protection. In 2024, the US government will start adopting new encryption rules and a phase out of existing encryption. There is a study being released next year …
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 …
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 …
On 4 December, IBMs new Quantum Chip called Condo with 1,121 superconducting qubits arranged in a honeycomb pattern was revealed. It follows on from its other record-setting, bird-named machines, including a 127-qubit chip in 2021 and a 433-qubit one last year. IBM also unveiled a chip called Heron that has 133 qubits, but with a …
IBM has a new quantum computing roadmap out to 2033 but the critical turning point is around 2029 when IBM goes from error mitigation to error correction. Quantum error suppression and error mitigation is making a substantial difference now as is shown by peer reviewed work by Q-CTRL. The IBM projections seem to be guiding …
IBM Quantum System Two is the building block of quantum-centric supercomputing. IBM Quantum System Two is the bedrock for scalable quantum computation. It is now operational at IBMs lab in Yorktown Heights, NY. It is 22 feet wide, 12 feet high, and today features three IBM Quantum Heron processors. It combines cryogenic infrastructure with third-generation …
Atom Computing announced it has created a 1,225-site atomic array, currently populated with 1,180 qubits, in its next-generation quantum computing platform. This is the first time a company has crossed the 1,000-qubit threshold for a universal gate-based system, planned for release next year. It marks an industry milestone toward fault-tolerant quantum computers capable of solving …
Researcher show that n-bit integers can be factorized by independently running a quantum circuit with orders of magnitude fewer qubits many times. It then use polynomial-time classical post-processing. The correctness of the algorithm relies on a number-theoretic heuristic assumption reminiscent of those used in subexponential classical factorization algorithms. It is currently not clear if the …
