Statistical approach to quantum phase estimation
New Journal of Physics, 2021 We introduce a new statistical and variational approach to the phase estimation algorithm (PEA). Unlike the traditional and iterative PEAs which return only an eigenphase estimate, the proposed method can determine any unknown eigenstate–eigenphase pair ...

Quantum Phase Estimation by Compressed Sensing [PDF]
QuantumAs a signal recovery algorithm, compressed sensing is particularly effective when the data has low complexity and samples are scarce, which aligns natually with the task of quantum phase estimation (QPE) on early fault-tolerant quantum computers. In this

Phase estimation as a quantum nondemolition measurement [PDF]
, 2002 The phase estimation algorithm, which is at the heart of a variety of quantum algorithms, including Shor's factoring algorithm, allows a quantum computer to accurately determine an eigenvalue of an unitary operator. Quantum nondemolition measurements are a quantum mechanical procedure, used to overcome the standard quantum limit when measuring an ...

Quantum Phase Estimation Using Multivalued Logic [PDF]
2011 41st IEEE International Symposium on Multiple-Valued Logic, 2011 Quantum phase estimation (QPE) is one of the most important quantum algorithms which is used as a subroutine for other important quantum algorithms like Shor's factoring algorithm, simulation of quantum systems, quantum counting and QFT on arbitrary Zp.

Imperfect Distributed Quantum Phase Estimation [PDF]
Computational Science – ICCS 2020, 2020 In the near-term, the number of qubits in quantum computers will be limited to a few hundreds. Therefore, problems are often too large and complex to be run on quantum devices. By distributing quantum algorithms over different devices, larger problem instances can be run.
