Development and Demonstration of an Efficient Readout Error Mitigation Technique for use in NISQ Algorithms
Andrew Arrasmith, Andrew Patterson, Alice Boughton +1
The approximate state estimation and the closely related classical shadows methods allow for the estimation of complicated observables with relatively few shots. As these methods m…
Estimating expectation values using approximate quantum states
Marco Paini, Amir Kalev, Dan Padilha +1
We introduce an approximate description of an -qubit state, which contains sufficient information to estimate the expectation value of any observable to a precision that is uppe…
Quantum versus Classical Generative Modelling in Finance
Brian Coyle, Maxwell Henderson, Justin Chan Jin Le +3
Finding a concrete use case for quantum computers in the near term is still an open question, with machine learning typically touted as one of the first fields which will be impact…
An approximate description of quantum states
Marco Paini, Amir Kalev
We introduce an approximate description of an -qubit state, which contains sufficient information to estimate the expectation value of any observable with precision independent…
Spin tomography
G. M. D'Ariano, L. Maccone, M. Paini
We propose a tomographic reconstruction scheme for spin states. The experimental setup, which is a modification of the Stern-Gerlach scheme, can be easily performed with currently…
Quantum Tomography Via Group Theory
M. Paini
Amongst the multitude of state reconstruction techniques, the so-called "quantum tomography" seems to be the most fruitful. In this letter, I will start by developing the mathemati…
