Webthat we can compute decoherence rates of a logical qubit encoded in our system in presence of additionnal noise channels introduced in the model; in particular, setting the noise strength to zero, we will see that the intrinsic decoherence rate due to the imperfect stabilization of grid-states is exponentially small in 1= . 2 Stability analysis A physical qubit is a physical device that behaves as a two-state quantum system, used as a component of a computer system. [1] [2] A logical qubit is a physical or abstract qubit that performs as specified in a quantum algorithm or quantum circuit [3] subject to unitary transformations , has a long enough … Meer weergeven In quantum computing, a qubit is a unit of information analogous to a bit (binary digit) in classical computing, but it is affected by quantum mechanical properties such as superposition and entanglement which allow qubits to be … Meer weergeven • Quantum error correction and the quantum threshold theorem • Quantum computing § Obstacles Meer weergeven 1-bit and 2-bit quantum gate operations have been shown to be universal.
