According to reports in the US media, a Chinese team has claimed that their novel quantum code-breaking method might significantly shrink the size of a workable quantum computer.
According to South China Morning Post, the team, lead by Professor Long Guilu of Tsinghua University, asserted in a paper that their new method may lower the scale of a usable quantum computer to 372 qubits, which is even less than IBM’s Osprey. Osprey uses 433 qubits and is far from being able to break codes.
A new 433 qubit quantum processor, introduced by IBM in November of last year, has the potential to do complicated quantum computations far beyond the capabilities of any conventional computer.
