Quantum circuit complexity of one-dimensional topological phases [PDF]
, 2015 Topological quantum states cannot be created from product states with local quantum circuits of constant depth and are in this sense more entangled than topologically trivial states, but how entangled are they?

Reducing CNOT count in quantum Fourier transform for the linear nearest-neighbor architecture
Scientific Reports, 2023 Physical limitations of quantum hardware often necessitate nearest-neighbor (NN) architecture. When synthesizing quantum circuits using the basic gate library, which consists of CNOT and single-qubit gates, CNOT gates are required to convert a quantum ...

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 ...

Quantum circuits for isometries [PDF]
Physical Review A, 2016 We consider the decomposition of arbitrary isometries into a sequence of single-qubit and Controlled-NOT (C-NOT) gates. In many experimental architectures, the C-NOT gate is relatively 'expensive' and hence we aim to keep the number of these as low as possible.

Natural parametrized quantum circuit
Physical Review A, 2022 Noisy intermediate scale quantum computers are useful for various tasks such as state preparation and variational quantum algorithms. However, the non-Euclidean quantum geometry of parameterized quantum circuits is detrimental for these applications.
