Contemporary quantum computers function according to the distinctive principles that govern subatomic particles and other infinitesimally small entities.
Scientists from Rutgers, International Business Machines Corp., and associated research institutions demonstrated that a quantum computer can perform continuous self-examination and component recalibration throughout its operational cycle.
Scaling quantum computers will necessitate their ability to detect and rectify errors during operation, a function referred to as error correction, enabling the development of a fault-tolerant quantum computer.
A fault-tolerant quantum computer maintains accurate computations despite the frequent minor errors occurring in its individual quantum bits.
To build a fault-tolerant quantum computer, we have to make these checks and corrections not just once or twice, but a huge number of times during a calculation.
