From a week to less than a day: Speedup and scaling of coordinate-scaled exact exchange calculations in plane waves

Ursula Röthlisberger, Martin Peter Bircher

Exact exchange is a primordial ingredient in Kohn–Sham Density Functional Theory based Molecular Dynamics (MD) simulations whenever thermodynamic properties, kinetics, barrier heights or excitation energies have to be predicted with high accuracy. However, ...

Quantifying uncertain system outputs via the multilevel Monte Carlo method — Part I: Central moment estimation

Fabio Nobile, Sebastian Krumscheid, Michele Pisaroni

In this work we introduce and analyze a novel multilevel Monte Carlo (MLMC) estimator for the accurate approximation of central moments of system outputs affected by uncertainties. Central moments play a central role in many disciplines to characterize a r ...

ROS : Resource Constrained Oracle Synthesis for Quantum Computers

Giovanni De Micheli, Mathias Soeken, Giulia Meuli

We present a complete automatic synthesis framework for oracle functions—a central part in many quantum algorithms. The proposed framework for resource-constrained oracle synthesis (ROS) is an LUT-based hierarchical method where every step is specifically ...

Efficient Quantum Algorithms for GHZ and W States, and Implementation on the IBM Quantum Computer

Nicolas Macris, Clément Christian Javerzac-Galy, Kenichi Komagata, Marc-André Dupertuis, Chun Lam Chan, Fabien Gremion, Jarla Thiesbrummel, Romain Fournier

Efficient deterministic algorithms are proposed with logarithmic step complexities for the generation of entangled GHZ(N) and W-N states useful for quantum networks, and an implementation on the IBM quantum computer up to N = 16 is demonstrated. Improved q ...

Benefits and Challenges of Designing Cryogenic CMOS RF Circuits for Quantum Computers

Edoardo Charbon, Harald Arjan Robert Homulle, Fabio Sebastiano

Accurate and low-noise generation and amplification of microwave signals are required for the manipulation and readout of quantum bits (qubits). A fault-tolerant quantum computer operates at deep cryogenic temperatures (i.e.,

Two-step phase shifting interferometry based on orientation selective monogenic filtering

Pramod Rastogi, Rishikesh Dilip Kulkarni

We propose a phase step estimation algorithm in a two-step phase shifting interferometry setup based on orientation selective adaptive monogenic filtering (AMF). Initially, the AMF algorithm is used for the fringe pattern normalization. A minor modificatio ...

A Comparison of Greedy and Global Searches for Measurement-System Design in Bridge Load Testing

Ian Smith, Numa Joy Bertola

Due to conservative design models and safe construction practices, infrastructure often has significant yet-unknown reserve capacity that greatly exceeds code requirements. Reserve-capacity assessments lead to better asset-management decisions through eith ...

Compiling Permutations for Superconducting QPUs

Giovanni De Micheli, Mathias Soeken, Fereshte Mozafari Ghoraba, Bruno Schmitt Antunes

In this paper we consider the compilation of quantum state permutations into quantum gates for physical quantum computers. A sequence of generic single-target gates, which realize the input permutation, are extracted using a decomposition based reversible ...

A programmable two-qubit quantum processor in silicon

Pasquale Scarlino

A two-qubit quantum processor in a silicon device is demonstrated, which can perform the Deutsch–Josza algorithm and the Grover search algorithm. ...

Programming Quantum Computers Using Design Automation

Mathias Soeken

Recent developments in quantum hardware indicate that systems featuring more than 50 physical qubits are within reach. At this scale, classical simulation will no longer be feasible and there is a possibility that such quantum devices may outperform even c ...
