Fault-tolerance threshold for a distance-three quantum code
Ben W. Reichardt
The quantum error threshold is the highest (model-dependent) noise rate which we can tolerate and still quantum-compute to arbitrary accuracy. Although noise thresholds are frequen…
Quantum error correction of systematic errors using a quantum search framework
Ben W. Reichardt, Lov K. Grover
Composite pulses are a quantum control technique for canceling out systematic control errors. We present a new composite pulse sequence inspired by quantum search. Our technique ca…
Improved magic states distillation for quantum universality
Ben W. Reichardt
Given stabilizer operations and the ability to repeatedly prepare a single-qubit mixed state rho, can we do universal quantum computation? As motivation for this question, "magic s…
Improved ancilla preparation scheme increases fault-tolerant threshold
Ben W. Reichardt
We demonstrate an improved concatenated encoded ancilla preparation procedure. Simulations show that this procedure significantly increases the error threshold beneath which arbitr…
