composed of quantum-computational operations (quantum gates and measurements), and thus, it can be conducted by any type of quantum device. In addition, it can be applied to error mitigation for many other types of quantum noise effects as well as noisy quantum computing of long-depth quantum...
Incorporating protection against quantum errors into adiabatic quantum computing (AQC) is an important task due to the inevitable presence of decoherence. Here, we investigate an error-protected encoding of the AQC Hamiltonian, where qubit ensembles are
We describe and analyze an error mitigation technique that uses multiple pairs of parity checks to detect the presence of errors. Each pair of checks uses one ancilla qubit to detect a component of the error operator and represents one layer of the techn
Read: A new paper from IBM and UC Berkeley shows a useful application for 127-qubit quantum processors with error mitigation — and a path toward useful quantum computing. teams extracted accurate results from a quantum computer for a circuit that couldn’t be exactly simulated by a classical ...
In combination with thetheory of fault-tolerant quantum computing, Quantum error correction suggests that engineers can, in principle, build an arbitrarily large quantum computer that would be capable of arbitrarily long computations if operated correctly. This would be a stunningly powerful achievement....
We are researching a continuous path to quantum advantage. Today, error mitigation and suppression techniques are bringing our clients to the edge of quantum advantage. These techniques are a stepping stone towards a world of fault-tolerant computing, and this new LDPC code is bringing that world...
