An atomic interface between microwave and optical photons

, 2012
A complete physical approach to quantum information requires a robust interface among flying qubits, long-lifetime memory and computational qubits. Here we present a unified interface for microwave and optical photons, potentially connecting engineerable

A Classical Electrodynamic Approach in Quantum Physics

, 2018
The famous 1927 Solvay Conference was considered a turning point in the world of Physics. The scientific realists like Albert Einstein had lost and the instrumentalists like Niels Bohr had won the fundamental conflict. Since then Physics has followed the path of the instrumentalists in which Quantum Physics has been determined by the concept of ...

Differential Evolution for Many-Particle Adaptive Quantum Metrology [PDF]

, 2013
We devise powerful algorithms based on differential evolution for adaptive many-particle quantum metrology. Our new approach delivers adaptive quantum metrology policies for feedback control that are orders-of-magnitude more efficient and surpass the few-

The Locality Problem in Quantum Measurements

, 2010
The locality problem of quantum measurements is considered in the framework of the algebraic approach. It is shown that contrary to the currently widespread opinion one can reconcile the mathematical formalism of the quantum theory with the assumption of

Noisy intermediate-scale quantum simulation of the one-dimensional wave equation [PDF]

Physical Review Research
We design and implement quantum circuits for the simulation of the one-dimensional wave equation on the Quantinuum H1-1 quantum computer. The circuit depth of our approach scales as O(n2) for n qubits representing the solution on 2n grid points, and ...

Quantum Phase Estimation with Arbitrary Constant-precision Phase Shift Operators [PDF]

, 2011
While Quantum phase estimation (QPE) is at the core of many quantum algorithms known to date, its physical implementation (algorithms based on quantum Fourier transform (QFT)) is highly constrained by the requirement of high-precision controlled phase ...
