Quantum technology is an emergent and potentially disruptive discipline, with the ability to
affect many human activities. Quantum technologies are dual-use technologies, and as such …

Quantum random-access memory (QRAM) is a mechanism to access data (quantum or
classical) based on addresses which are themselves a quantum state. QRAM has a long …

Abstract Recently, Hastings & Haah introduced a quantum memory defined on the
honeycomb lattice. Remarkably, this honeycomb code assembles weight-six parity checks …

Cat qubits provide appealing building blocks for quantum computing. They exhibit a tunable
noise bias yielding an exponential suppression of bit flips with the average photon number …

In this survey, the authors review the main quantum algorithms for solving the computational
problems that serve as hardness assumptions for cryptosystem. To this end, the authors …

Quantum computing is an emerging technology with potentially far-reaching implications for
national prosperity and security. Understanding the timeframes over which economic …

Recent independent analyses by Bonnetain–Schrottenloher and Peikert in Eurocrypt 2020
significantly reduced the estimated quantum security of the isogeny-based commutative …

We refine ideas from Knill 1996, Jones 2016, Chamberland 2020, Gidney 2023+ 2024,
Bombin 2024, and Hirano 2024 to efficiently prepare good $| T\rangle $ states. We call our …

In the race to build scalable quantum computers, minimizing the resource consumption of
their full stack to achieve a target performance becomes crucial. It mandates a synergy of …

Existing experimental demonstrations of quantum computational advantage have had the
limitation that verifying the correctness of the quantum device requires exponentially costly …
