Qiskit Backend Specifications for OpenQASM and OpenPulse Experiments
D. McKay, Thomas Alexander, Luciano Bello +17 more·Sep 10, 2018
As interest in quantum computing grows, there is a pressing need for standardized API's so that algorithm designers, circuit designers, and physicists can be provided a common reference frame for designing, executing, and optimizing experiments. Ther...
Quantum Hamiltonian Identifiability via a Similarity Transformation Approach and Beyond
Yuanlong Wang, Daoyi Dong, A. Sone +3 more·Sep 9, 2018
The identifiability of a system is concerned with whether the unknown parameters in the system can be uniquely determined with all the possible data generated by a certain experimental setting. A test of quantum Hamiltonian identifiability is an impo...
Quantum algorithm for nonhomogeneous linear partial differential equations
J. Arrazola, Timjan Kalajdzievski, C. Weedbrook +1 more·Sep 8, 2018
We describe a quantum algorithm for preparing states that encode solutions of non-homogeneous linear partial differential equations. The algorithm is a continuous-variable version of matrix inversion: it efficiently inverts differential operators tha...
Tackling the Qubit Mapping Problem for NISQ-Era Quantum Devices
Gushu Li, Yufei Ding, Yuan Xie·Sep 7, 2018
Due to little considerations in the hardware constraints, e.g., limited connections between physical qubits to enable two-qubit gates, most quantum algorithms cannot be directly executed on the Noisy Intermediate-Scale Quantum (NISQ) devices. Dynamic...
Photonic quantum algorithm for Monte Carlo integration
P. Rebentrost, Brajesh Gupt, T. Bromley·Sep 7, 2018
We present a continuous-variable photonic quantum algorithm for the Monte Carlo evaluation of multi-dimensional integrals. Our algorithm encodes n-dimensional integration into n+3 modes and can provide a quadratic speedup in runtime compared to the c...
Classical simulability of noisy boson sampling
J. Renema, V. Shchesnovich, R. García-Patrón·Sep 6, 2018
Quantum mechanics promises computational powers beyond the reach of classical computers. Current technology is on the brink of an experimental demonstration of the superior power of quantum computation compared to classical devices. For such a demons...
A Comparison of the Bravyi–Kitaev and Jordan–Wigner Transformations for the Quantum Simulation of Quantum Chemistry
A. Tranter, P. Love, F. Mintert +1 more·Sep 6, 2018
The ability to perform classically intractable electronic structure calculations is often cited as one of the principal applications of quantum computing. A great deal of theoretical algorithmic development has been performed in support of this goal....

Gate-based single-shot readout of spins in silicon
A. West, B. Hensen, A. Jouan +8 more·Sep 6, 2018
Electron spins in silicon quantum dots provide a promising route towards realizing the large number of coupled qubits required for a useful quantum processor1–7. For the implementation of quantum algorithms and error detection8–10, qubit measurements...
Accurate Quantum Logic Gates by Spin Echo in Rydberg Atoms
Xiao-Feng Shi·Sep 5, 2018
Scalable quantum computing is based on realizable accurate quantum gates. For neutral atoms, it is an outstanding challenge to design a high-fidelity two-qubit entangling gate without resorting to difficult techniques like shaping laser pulses or coo...

Yongshan Ding, Adam Holmes, Ali JavadiAbhari +3 more·Sep 5, 2018
Quantum computers have recently made great strides and are on a long-term path towards useful fault-tolerant computation. A dominant overhead in fault-tolerant quantum computation is the production of high-fidelity encoded qubits, called magic states...
The quantum version of the shifted power method and its application in quadratic binary optimization
