Reinforcement Learning for Robust Calibration of Multi-Qudit Quantum Gates
Amine Jaouadi, Sahel Ashhab
Higher-dimensional quantum systems, such as qudits, offer architectural and algorithmic advantages over qubits, but their increased spectral crowding and limited controllability re…
Control the qubit-qubit coupling with double superconducting resonators
Hui Wang, Rui Wang, Daichi Sugiyama +5
We experimentally studied the switching off processes in the double-resonator coupler superconducting quantum circuit. In both frequency and time-domain, we observed the variation…
Reply to Comment on "Properties and dynamics of generalized squeezed states"
Sahel Ashhab, Mohammad Ayyash
In our paper [1], our numerical simulations showed that, unlike displacement and conventional squeezing, higher-order squeezing exhibits oscillatory dynamics. Subsequently, Gordill…
Fractional squeezing: spectra and dynamics from generalized squeezing Hamiltonian with fractional orders
Sahel Ashhab
We generalize the generalized-squeezing problem to include fractional values of the squeezing order . This approach allows us to determine the locations of critical points at wh…
Finite-dimensional approximations of generalized squeezing
Sahel Ashhab, Felix Fischer, Davide Lonigro +2
We show unexpected behaviour in simulations of generalized squeezing performed with finite-dimensional truncations of the Fock space: even for extremely large dimension of the stat…
Physically motivated decompositions of single-qutrit gates
Aryan Iliat, Mark Byrd, Sahel Ashhab +1
Although only two quantum states of a physical system are often used to encode quantum information in the form of qubits, many levels can in principle be used to obtain qudits and…
