A unified picture of Balance puzzles and Group testing: Some lessons from quantum mechanics for the pandemic
Chetan Waghela·Aug 4, 2021
Balance (Counterfeit coin) puzzles have been part of recreational mathematics for a few decades. A particular type of Counterfeit coin puzzle is known in the literature as the"Beam balance puzzle". An abstract solution to it is provided by Iwama et.a...
Towards Demonstrating Fault Tolerance in Small Circuits Using Bacon-Shor Codes
Ariel Shlosberg, A. Polloreno, Graeme Smith·Aug 4, 2021
Quantum error correction is necessary to perform large-scale quantum computations in the presence of noise and decoherence. As a result, several aspects of quantum error correction have already been explored. These have been primarily studies of quan...
2QAN: a quantum compiler for 2-local qubit hamiltonian simulation algorithms
L. Lao, D. Browne·Aug 4, 2021
Simulating quantum systems is one of the most important potential applications of quantum computers. The high-level circuit defining the simulation needs to be compiled into one that complies with hardware limitations such as qubit architecture (conn...
Fault-Tolerant Syndrome Extraction and Cat State Preparation with Fewer Qubits
Prithviraj Prabhu, B. Reichardt·Aug 4, 2021
We reduce the extra qubits needed for two fault-tolerant quantum computing protocols: error correction, specifically syndrome bit measurement, and cat state preparation. For distance-three fault-tolerant syndrome extraction, we show an exponential re...
Variational quantum eigensolver for the Heisenberg antiferromagnet on the kagome lattice
Joris Kattemölle, Jasper van Wezel·Aug 4, 2021
Establishing the nature of the ground state of the Heisenberg antiferromagnet (HAFM) on the kagome lattice is well known to be a prohibitively difficult problem for classical computers. Here, we give a detailed proposal for a Variational Quantum Eige...
On-chip scalable highly pure and indistinguishable single-photon sources in ordered arrays: Path to quantum optical circuits
Jiefei Zhang, Swarnabha Chattaraj, Qi Huang +3 more·Aug 3, 2021
Realization of quantum optical circuits is at the heart of quantum photonic information processing. A long-standing obstacle, however, has been the absence of a suitable platform of single photon sources (SPSs). Such SPSs need to be in spatially orde...
Generalized quantum circuit differentiation rules
O. Kyriienko, V. Elfving·Aug 3, 2021
Variational quantum algorithms that are used for quantum machine learning rely on the ability to automatically differentiate parametrized quantum circuits with respect to underlying parameters. Here, we propose the rules for differentiating quantum c...
