Anomalous diffusion in the Long-Range Haken-Strobl-Reineker model
Alberto Giuseppe Catalano, Francesco Mattiotti, Jérôme Dubail +4
We analyze the propagation of excitons in a -dimensional lattice with power-law hopping in the presence of dephasing, described by a generalized Haken-Strobl-Rei…
Orthogonally Constrained Orbital Optimization: assessing changes of optimal orbitals for orthogonal multi-reference states
Saad Yalouz, Vincent Robert
The choice of molecular orbitals is decisive in configuration interaction calculations. In this letter, a democratic description of the ground and excited states follows an orthogo…
Optimizing Rydberg Gates for Logical Qubit Performance
Sven Jandura, Jeff D Thompson, Guido Pupillo
Robust gate sequences are widely used to reduce the sensitivity of gate operations to experimental imperfections. Typically, the optimization minimizes the average gate error, howe…
Robust phase-controlled gates for scalable atomic quantum processors using optical standing waves
Shannon Whitlock
A simple scheme is presented for realizing robust optically controlled quantum gates for scalable atomic quantum processors by driving the qubits with optical standing waves. Atoms…
Out-of-time-order correlators and quantum chaos
Ignacio García-Mata, Rodolfo A. Jalabert, Diego A. Wisniacki
Quantum Chaos has originally emerged as the field which studies how the properties of classical chaotic systems arise in their quantum counterparts. The growing interest in quantum…
Pseudo-PT symmetric Dirac equation : effect of a new mean spin angular momentum operator on Gilbert damping
Y. Bouguerra, S. Mehani, K. Bechane +2
The pseudo-PT symmetric Dirac equation is proposed and analyzed by using a non-unitary Foldy-Wouthuysen transformations. A new spin operator PT symmetric expectation value (called…
Quantum embedding of multi-orbital fragments using the Block-Householder-transformation
Saad Yalouz, Sajanthan Sekaran, Emmanuel Fromager +1
Recently, some of the authors introduced the use of the Householder transformation as a simple and intuitive method for the embedding of local molecular fragments (see Sekaran et.…
Emergence of Spinmerism for Molecular Spin-Qubits Generation
Roseiro Pablo, Petit Louis, Robert Vincent +1
Molecular platforms are regarded as promising candidates in the generation of units of information for quantum computing. Herein, a strategy combining spin-crossover metal ions and…
Toward Density Functional Theory on Quantum Computers?
Bruno Senjean, Saad Yalouz, Matthieu Saubanère
Quantum Chemistry and Physics have been pinpointed as killer applications for quantum computers, and quantum algorithms have been designed to solve the Schrödinger equation with th…
Time-Optimal Two- and Three-Qubit Gates for Rydberg Atoms
Sven Jandura, Guido Pupillo
We identify time-optimal laser pulses to implement the controlled-Z gate and its three qubit generalization, the CZ gate, for Rydberg atoms in the blockade regime. Pulses are o…
Rise and fall, and slow rise again, of operator entanglement under dephasing
David Wellnitz, Guillermo Preisser, Vincenzo Alba +2
The operator space entanglement entropy, or simply 'operator entanglement' (OE), is an indicator of the complexity of quantum operators and of their approximability by Matrix Produ…
Logical Entropy and Negative Probabilities in Quantum Mechanics
Giovanni Manfredi
The concept of Logical Entropy, , where the are normalized probabilities, was introduced by David Ellerman in a series of recent papers. Although…
