Harvard, QuEra, MIT, and the NIST/University of Maryland Usher in New Era of Quantum Computing by Performing Complex, Error-Corrected Quantum Algorithms on 48 Logical Qubits
A critical challenge preventing quantum computing from reaching its enormous potential is the noise that affects qubits, corrupting computations before reaching the desired results.
- A critical challenge preventing quantum computing from reaching its enormous potential is the noise that affects qubits, corrupting computations before reaching the desired results.
- Quantum error correction overcomes these limitations by creating “logical qubits," groups of physical qubits that are entangled to store information redundantly.
- This new work demonstrates quantum error correction in 48 logical qubits, enhancing computational stability and reliability while addressing the error problem.
- Realization of 48 small logical qubits that were used to execute complex algorithms, surpassing the performance of the same algorithms when executed with physical qubits.
