The second requirement will be a lot more hardware qubits—having 32 hardware qubits limits the error-correction system tests that can be done on the current hardware.

A quantum computer corrected its own errors, improving its calculations It’s a step in the right direction for reliable quantum computing ...

In contrast to classical computers, which operate on bits that can only take the basic values 0 and 1, quantum computers operate on "qubits," which can assume any superposition of the ...

A bosonic qubit turns that situation on its head. In this hardware, the quantum information is held in the photons, while the superconducting wire and resonator control the system. These are both ...

The most famous examples of locally correctable codes are versions of a venerable error-correcting code invented in 1954 by the mathematicians David Muller and Irving Reed (who also helped develop ...

The firm also saw benefits that could come as quantum computers scale up, such as longer system lifespans (by reducing “silent” errors) and information that could lead to further error-correction ...

That’s why the field is racing to develop and implement quantum error-correction (QEC) schemes to alleviate the technology’s inherent unreliability. These approaches involve building ...

Quantum computing breakthroughs from IonQ, D-Wave, QuEra, Alice & Bob, and others in the last six months, with dates, achievements, and their impact on error-corrected, scalable quantum systems. May 7 ...
