Analysis of measurement errors for a superconducting phase qubit
We analyze several mechanisms leading to errors in a course of measurement of a superconducting fluxbiased phase qubit. Insufficiently long measurement pulse may lead to nonadiabatic transitions between qubit states 1 and 0 , before tunneling through a reduced barrier is supposed to distinguish the qubit states. Finite though large ratio of tunneling rates for these states leads to incomplete d...

متن کاملReversal of the weak measurement of a quantum state in a superconducting phase qubit.
We demonstrate in a superconducting qubit the conditional recovery (uncollapsing) of a quantum state after a partial-collapse measurement. A weak measurement extracts information and results in a nonunitary transformation of the qubit state. However, by adding a rotation and a second partial measurement with the same strength, we erase the extracted information, canceling the effect of both mea...
متن کاملMeasurement and control of quasiparticle dynamics in a superconducting qubit.
Superconducting circuits have attracted growing interest in recent years as a promising candidate for fault-tolerant quantum information processing. Extensive efforts have always been taken to completely shield these circuits from external magnetic fields to protect the integrity of the superconductivity. Here we show vortices can improve the performance of superconducting qubits by reducing th...
متن کاملMeasurement of geometric dephasing using a superconducting qubit
A quantum system interacting with its environment is subject to dephasing, which ultimately destroys the information it holds. Here we use a superconducting qubit to experimentally show that this dephasing has both dynamic and geometric origins. It is found that geometric dephasing, which is present even in the adiabatic limit and when no geometric phase is acquired, can either reduce or restor...
