Optimized Telecloning Circuits: Theory and Practice of Nine NISQ Clones
Elijah Pelofske, Andreas Bärtschi, Stephan Eidenbenz
Although perfect copying of an unknown quantum state is not possible, approximate cloning is possible in quantum mechanics. Quantum telecloning is a variant of approximate quantum…
Scalable Experimental Bounds for Entangled Quantum State Fidelities
Shamminuj Aktar, Andreas Bärtschi, Abdel-Hameed A. Badawy +1
Estimating the state preparation fidelity of highly entangled states on noisy intermediate-scale quantum (NISQ) devices is important for benchmarking and application considerations…
Short-Depth Circuits for Dicke State Preparation
Andreas Bärtschi, Stephan Eidenbenz
We present short-depth circuits to deterministically prepare any Dicke state |Dn,k>, which is the equal-amplitude superposition of all n-qubit computational basis states with Hammi…
A near-term quantum algorithm for solving linear systems of equations based on the Woodbury identity
Daniel O'Malley, Jessie M. Henderson, Elijah Pelofske +5
Quantum algorithms for solving linear systems of equations have generated excitement because of the potential speed-ups involved and the importance of solving linear equations in m…
Quantum Telecloning on NISQ Computers
Elijah Pelofske, Andreas Bärtschi, Bryan Garcia +2
Due to the no-cloning theorem, generating perfect quantum clones of an arbitrary unknown quantum state is not possible, however approximate quantum clones can be constructed. Quant…
Quantum Volume in Practice: What Users Can Expect from NISQ Devices
Elijah Pelofske, Andreas Bärtschi, Stephan Eidenbenz
Quantum volume (QV) has become the de-facto standard benchmark to quantify the capability of Noisy Intermediate-Scale Quantum (NISQ) devices. While QV values are often reported by…
