Quantum computing researchers are exploring whether quantum computational advantage might be obtainable without quantum error correction. The larger one can make a quantum computer while continuing to push down error rates the more likely it is that we will find tasks at which non-error-corrected quantum computers dramatically outperform the best classical algorithms. The high gate …
Nextbigfuture interviewed the President and COO of Quantinuum, Tony Uttley, and the scientific lead, Dr Henrik Dreyer. They have used the new H2 32 Qubit quantum computer chip to engineer the waveform of a new state of matter. They have engineered something called the Non-Abelian Topological Quantum state. Topological quantum computing has been one of …
Google has a quantum computing goal of encoding a logical qubit on 1000 physical ones with an error rate of 0.0001% and they have achieved a 3% error rate using 17 qubits. The scaling or error reduction must be 20 times better. Using a 72-qubit chip, the Google team encoded a single logical qubit in …
Cambridge Quantum, a leader quantum software, and Honeywell Quantum, a leader in trapped ion quantum hardware, have merged. The new company, which will be formally named in due course, will have a long-term agreement with Honeywell to help manufacture the critical ion traps needed to power the quantum hardware. Honeywell will invest between US$270million to …
