Quantum feature encoding optimization
Tommaso Fioravanti, Brian Quanz, Gabriele Agliardi +3
Quantum Machine Learning (QML) holds the promise of enhancing machine learning modeling in terms of both complexity and accuracy. A key challenge in this domain is the encoding of…
Efficient solution of the non-unitary time-dependent Schrodinger equation on a quantum computer with complex absorbing potential
Mariane Mangin-Brinet, Jing Zhang, Denis Lacroix +1
We explore the possibility of adding complex absorbing potential at the boundaries when solving the one-dimensional real-time Schrödinger evolution on a grid using a quantum comput…
Restoring broken symmetries using oracles
Edgar Andres Ruiz Guzman, Denis Lacroix
We present a new method to perform variation after projection in many-body systems on quantum computers that does not require performing explicit projection. The technique employs…
Accessing ground state and excited states energies in many-body system after symmetry restoration using quantum computers
E. A. Ruiz Guzman, D. Lacroix
We explore the possibility to perform symmetry restoration with the variation after projection technique on a quantum computer followed by additional post-processing. The final goa…
Calculation of generating function in many-body systems with quantum computers: technical challenges and use in hybrid quantum-classical methods
Edgar Andres Ruiz Guzman, Denis Lacroix
The generating function of a Hamiltonian is defined as , where is the time and where the expectation value is taken on a given initial quantum…
Geometric Phase of a Spin-1/2 Particle Coupled to a Quantum Vector Operator
Pedro Aguilar, Chryssomalis Chryssomalakos, Edgar Guzman
We calculate Berry's phase when the driving field, to which a spin-1/2 is coupled adiabatically, rather than the familiar classical magnetic field, is a quantum vector operator, of…
