Quantum Circuits for Sparse Isometries [PDF]

open access: yesQuantum, 2021
We consider the task of breaking down a quantum computation given as an isometry into C-NOTs and single-qubit gates, while keeping the number of C-NOT gates small. Although several decompositions are known for general isometries, here we focus on a method based on Householder reflections that adapts well in the case of sparse isometries. We show how to

Quantum Circuit Synthesis Using Projective Simulation

open access: yesInteligencia Artificial, 2021
Quantum Computing has been evolving in the last years. Although nowadays quantum algorithms performance has shown superior to their classical counterparts, quantum decoherence and additional auxiliary qubits needed for error tolerance routines have been ...

Simulating Large Quantum Circuits on a Small Quantum Computer [PDF]

open access: yes, 2020
Limited quantum memory is one of the most important constraints for near-term quantum devices. Understanding whether a small quantum computer can simulate a larger quantum system, or execute an algorithm requiring more qubits than available, is both of ...

Variational Power of Quantum Circuit Tensor Networks

open access: yesPhysical Review X, 2022
We characterize the variational power of quantum circuit tensor networks in the representation of physical many-body ground states. Such tensor networks are formed by replacing the dense block unitaries and isometries in standard tensor networks by local

Teleportation as a quantum computation [PDF]

open access: yes, 1996
An explicit quantum circuit is given to implement quantum teleportation. This circuit makes teleportation straightforward to anyone who believes that quantum computation is a reasonable proposition.

Quantum circuit debugging and sensitivity analysis via local inversions [PDF]

open access: yesQuantum, 2023
As the width and depth of quantum circuits implemented by state-of-the-art quantum processors rapidly increase, circuit analysis and assessment via classical simulation are becoming unfeasible. It is crucial, therefore, to develop new methods to identify

Quantum Memristors with Superconducting Circuits [PDF]

open access: yesScientific Reports, 2017
AbstractMemristors are resistive elements retaining information of their past dynamics. They have garnered substantial interest due to their potential for representing a paradigm change in electronics, information processing and unconventional computing.
