Ability of stabilizer quantum error correction to protect itself from its own imperfection
Yuichiro Fujiwara
The theory of stabilizer quantum error correction allows us to actively stabilize quantum states and simulate ideal quantum operations in a noisy environment. It is critical is to…
Using arbitrary parity-check matrices for quantum error correction assisted by less noisy qubits
Yuichiro Fujiwara
Recently a framework for assisted quantum error correction was proposed in which a specific type of error is allowed to occur on auxiliary qubits, which is in contrast to standard…
Instantaneous Quantum Channel Estimation during Quantum Information Processing
Yuichiro Fujiwara
We present a nonintrusive method for reliably estimating the noise level during quantum computation and quantum communication protected by quantum error-correcting codes. As prepro…
Quantum synchronizable codes from finite geometries
Yuichiro Fujiwara, Peter Vandendriessche
Quantum synchronizable error-correcting codes are special quantum error-correcting codes that are designed to correct both the effect of quantum noise on qubits and misalignment in…
High-rate quantum low-density parity-check codes assisted by reliable qubits
Yuichiro Fujiwara, Alexander Gruner, Peter Vandendriessche
Quantum error correction is an important building block for reliable quantum information processing. A challenging hurdle in the theory of quantum error correction is that it is si…
Algebraic techniques in designing quantum synchronizable codes
Yuichiro Fujiwara, Vladimir D. Tonchev, Tony W. H. Wong
Quantum synchronizable codes are quantum error-correcting codes that can correct the effects of quantum noise as well as block synchronization errors. We improve the previously kno…
