Recursive Encoding and Decoding of Noiseless Subsystem and Decoherence Free Subspace
Chi-Kwong Li, Mikio Nakahara, Yiu-Tung Poon +2
When the environmental disturbace to a quantum system has a wavelength much larger than the system size, all qubits localized within a small area are under action of the same error…
Efficient Quantum Error Correction for Fully Correlated Noise
Chi-Kwong Li, Mikio Nakahara, Yiu-Tung Poon +2
We investigate an efficient quantum error correction of a fully correlated noise. Suppose the noise is characterized by a quantum channel whose error operators take fully correlate…
Recovery in quantum error correction for general noise without measurement
Chi-Kwong Li, Mikio Nakahara, Yiu-Tung Poon +2
It is known that one can do quantum error correction without syndrome measurement, which is often done in operator quantum error correction (OQEC). However, the physical realizatio…
Unitary Quantum Error Correction without Error Detection
Hiroyuki Tomita, Mikio Nakahara
We propose a quantum error correction without error detection. A quantum state combined with an ancilla state is encoded unitarily and an error operator is applied on the…
