Distributions of Noisy Expectation Values over Sets of Measurement Operators
Matthew Duschenes, Roger G. Melko, Juan Carrasquilla +1
Expectation values of measurement operators, interpreted as measurement probabilities, arise frequently throughout quantum algorithms. When quantum states are randomly distributed,…
Quantum Error Corrected Non-Markovian Metrology
Zachary Mann, Ningping Cao, Raymond Laflamme +1
Quantum metrology aims to maximize measurement precision on quantum systems, with a wide range of applications in quantum sensing. Achieving the Heisenberg limit (HL) - the fundame…
Theory of quasi-exact fault-tolerant quantum computing and valence-bond-solid codes
Dong-Sheng Wang, Yun-Jiang Wang, Ningping Cao +2
In this work, we develop the theory of quasi-exact fault-tolerant quantum (QEQ) computation, which uses qubits encoded into quasi-exact quantum error-correction codes ("quasi codes…
Efficient state initialization by a quantum spectral filtering algorithm
F. Fillion-Gourdeau, S. MacLean, R. Laflamme
An algorithm that initializes a quantum register to a state with a specified energy range is given, corresponding to a quantum implementation of the celebrated Feit-Fleck method. T…
