We propose to utilize NISQ-era quantum devices to compute short distance quantities in (2 + 1)-
dimensional QED and to combine them with large volume Monte Carlo simulations and perturbation
theory. Since the theory is asymptotically free, it would serve as a training ground for future studies of Quantum Chromodynamics in (3 + 1)-dimensions on quantum computers. From the definition of the...
Variational hybrid classical-quantum algorithms such as the Variational Quantum Eigensolver represent a major research field in the era of Noisy-Intermediate Scale Quantum (NISQ) devices [1]. The use of such algorithms promises advances in many sciences such as solid-state and high-energy physics as well as in quantum chemistry, where a proper understanding of electron-correlation is decisive...
The Quantum Angle Generator (QAG) is a new generative model for quantum computers and described in this paper. The QAG model consists of a parameterized quantum circuit trained with an objective function. It utilizes angle encoding for the conversion between the generated quantum data and classical data. Therefore, it requires one qubit per feature or pixel, while the output resolution is...
Often running quantum circuits on real hardware is time consuming due to queueing. For problems where the circuit size is small, and in order to maximise the output of a single execution, different instances of the circuit can be run simultaneously.
As an example, a small Quantum Circuit Born Machine is trained using the parameter shift rule, which requires the circuit to be run twice with a...
Particle track reconstruction poses a key computing challenge for future collider experiments. Quantum computing carries the potential for exponential speedups and the rapid progress in quantum hardware might make it possible to address the problem of particle tracking in the near future.
The solution of the tracking problem can be encoded in the ground state of a quadratic unconstrained...
We work on the Kogut-Susskind Hamiltonian formulation for the (2+1)d QED with open boundary conditions for a ladder lattice with up to 5 plaquettes. We add a pairs of external static charges at variable distances in an attempt to investigate confinement and we study the static force for variable values of coupling and the kinetic strength. We also identify the states of maximal translational...
Classical and quantum Boltzmann machines for analyzing medical data.
In this talk, we will be looking at quantum circuits comprising parametric gates and analyze their expressivity in terms of the space of states that can be generated by a given circuit.
A standard tool in quantum computing are Variational Quantum Simulations (VQS) which form a class of hybrid quantum-classical algorithms for solving optimization problems. For example, the objective may be...
