Furthermore, more » the protocol increases the relaxation time of the protected logical qubit by a factor of 2.7 over the relaxation times of the bare comprising qubits. An FPGA controller actively corrects errors as they are detected, achieving an average bit-flip detection efficiency of up to 91%. Here we use direct parity measurements to implement a continuous quantum bit-flip correction code in a resource-efficient manner, eliminating entangling gates, ancillary qubits, and their associated errors. Typically, quantum error correction is executed in discrete rounds, using entangling gates and projective measurement on ancillary qubits to complete each round of error correction. A powerful method to suppress these effects is quantum error correction. The storage and processing of quantum information are susceptible to external noise, resulting in computational errors. This leads to lower bounds on the number of qubits required to correct e errors and a formal proof that the classical bounds on the probability of error of e-error-correcting codes applies to e-error-correcting quantum codes, provided that the interaction is dominated by an identity component. A formal definition of independent interactions for qubits is given. We show that the error for entangled states is bounded linearly by the error for pure states. The latter is more appropriate when using codes in a quantum memory or in applications of quantum teleportation to communication. Two notions of fidelity and error for imperfect recovery are introduced, one for pure and the other for entangled states. We relate this definition to four others: the existence of a left inverse of the interaction, more » an explicit representation of the error syndrome using tensor products, perfect recovery of the completely entangled state, and an information theoretic identity. We use them to give a recovery-operator-independent definition of error-correcting codes. The conditions depend only on the behavior of the logical states. We obtain necessary and sufficient conditions for the perfect recovery of an encoded state after its degradation by an interaction. We develop a general theory of quantum error correction based on encoding states into larger Hilbert spaces subject to known interactions. Quantum error correction will be necessary for preserving coherent states against noise and other unwanted interactions in quantum computation and communication.
