Whilst classical bit-flip detection can be realized via a linear array of qubits, a general fault-tolerant quantum error-correcting code requires extending into a higher-dimensional lattice.

A sad truth of life is that bits will occasionally fail in a PROM, corrupting the program code. The checksum for valid code is written at one end of the PROM’s memory for verification at startup ...

Canada ‘a sweet spot’ for growing quantum computing industry, expert says. Christian Weedbrook, Xanadu’s founder and chief executive officer, said the development means it is possible to ...
