Privacy and correctness trade-offs for information-theoretically secure quantum homomorphic encryption [PDF]
Quantum, 2023 Quantum homomorphic encryption, which allows computation by a server directly on encrypted data, is a fundamental primitive out of which more complex quantum cryptography protocols can be built.

Quantum Circuit Synthesis Using Projective Simulation
Inteligencia 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 ...

Quantum circuits for quantum channels [PDF]
Physical Review A, 2017 We study the implementation of quantum channels with quantum computers while minimizing the experimental cost, measured in terms of the number of Controlled-NOT (C-NOT) gates required (single-qubit gates are free). We consider three different models. In the first, the Quantum Circuit Model (QCM), we consider sequences of single-qubit and C-NOT gates ...

Circuit Quantum Electrodynamics with Carbon-Nanotube-Based Superconducting Quantum Circuits [PDF]
Physical Review Applied, 2021 Hybrid circuit QED involves the study of coherent quantum physics in solid-state systems via their interactions with superconducting microwave circuits. Here we present a crucial step in the implementation of a hybrid superconducting qubit that employs a carbon nanotube as a Josephson junction.

Variational Power of Quantum Circuit Tensor Networks
Physical 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

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

Sparse Quantum Codes from Quantum Circuits [PDF]
Proceedings of the forty-seventh annual ACM symposium on Theory of Computing, 2015 We describe a general method for turning quantum circuits into sparse quantum subsystem codes. The idea is to turn each circuit element into a set of low-weight gauge generators that enforce the input-output relations of that circuit element. Using this prescription, we can map an arbitrary stabilizer code into a new subsystem code with the same ...
