Qubit circuit

Facts for Prelims (FFP)

 Context: Researchers at MIT have made significant progress in developing a novel superconducting qubit architecture that can perform operations between qubits with much greater accuracy than previously achieved.

  • They used a relatively new type of superconducting qubit called fluxonium, which has a longer lifespan than traditional superconducting qubits.
  • This allowed them to achieve single-qubit gates with 99.99% accuracy and two-qubit gates with 99.9% accuracy, well above the threshold needed for certain error-correcting codes.


Fluxonium is a type of qubit (quantum bit) that is based on operations at important junctions in a superconducting circuit

Quantum computing is a multidisciplinary field that utilizes quantum mechanics to solve complex problems faster than classical computers. A qubit is the basic unit of information in quantum computing
