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…
Filtering states with total spin on a quantum computer
Pooja Siwach, Denis Lacroix
Starting from a general wave function described on a set of spins/qubits, we propose several quantum algorithms to extract the components of this state on eigenstates of the total…
New type of self-oscillating systems
V. V. Sargsyan, A. A. Hovhannisyan, G. G. Adamian +2
The time evolution of occupation number is studied for a bosonic oscillator (with one and two degrees of freedom) linearly fully coupled to fermionic and bosonic heat baths. The ab…
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…
