Snakes and Ladders: Adapting the surface code to defects
Catherine Leroux, Sophia F. Lin, Przemyslaw Bienias +4
One of the critical challenges solid-state quantum processors face is the presence of fabrication imperfections and two-level systems, which render certain qubits and gates either…
Impact of Josephson junction array modes on fluxonium readout
Shraddha Singh, Gil Refael, Aashish Clerk +1
Dispersive readout of superconducting qubits is often limited by readout-drive-induced transitions between qubit levels. While there is a growing understanding of such effects in t…
Exploring the quantum capacity of a Gaussian random displacement channel using Gottesman-Kitaev-Preskill codes and maximum likelihood decoding
Mao Lin, Kyungjoo Noh
Determining the quantum capacity of a noisy quantum channel is an important problem in the field of quantum communication theory. In this work, we consider the Gaussian random disp…
Hybrid cat-transmon architecture for scalable, hardware-efficient quantum error correction
Connor T. Hann, Kyungjoo Noh, Harald Putterman +6
Dissipative cat qubits are a promising physical platform for quantum computing, since their large noise bias can enable more hardware-efficient quantum error correction. In this wo…
Robust Noise Suppression and Quantum Sensing by Continuous Phased Dynamical Decoupling
Daniel Louzon, Genko T. Genov, Nicolas Staudenmaier +5
We propose and demonstrate experimentally continuous phased dynamical decoupling (CPDD), where we apply a continuous field with discrete phase changes for quantum sensing and robus…
Optimal Conversion from Classical to Quantum Randomness via Quantum Chaos
Wai-Keong Mok, Tobias Haug, Adam L. Shaw +2
Quantum many-body systems provide a unique platform for exploring the rich interplay between chaos, randomness, and complexity. In a recently proposed paradigm known as deep therma…
Preserving phase coherence and linearity in cat qubits with exponential bit-flip suppression
Harald Putterman, Kyungjoo Noh, Rishi N. Patel +17
Cat qubits, a type of bosonic qubit encoded in a harmonic oscillator, can exhibit an exponential noise bias against bit-flip errors with increasing mean photon number. Here, we foc…
Decomposition Pipeline for Large-Scale Portfolio Optimization with Applications to Near-Term Quantum Computing
Atithi Acharya, Romina Yalovetzky, Pierre Minssen +10
Industrially relevant constrained optimization problems, such as portfolio optimization and portfolio rebalancing, are often intractable or difficult to solve exactly. In this work…
Optimizing quantum error correction protocols with erasure qubits
Shouzhen Gu, Yotam Vaknin, Alex Retzker +1
Erasure qubits offer a promising avenue toward reducing the overhead of quantum error correction (QEC) protocols. However, they require additional operations, such as erasure check…
Cross-resonance control of an oscillator with an auxiliary fluxonium qubit
Guo Zheng, Simon Lieu, Emma L. Rosenfeld +2
The conditional displacement (CD) gate between an oscillator and a discrete-variable auxiliary qubit plays a key role in quantum information processing tasks, such as enabling univ…
State-dependent mobility edge in kinetically constrained models
Manthan Badbaria, Nicola Pancotti, Rajeev Singh +2
In this work, we show that the kinetically constrained quantum East model lies between a quantum scarred and a many-body localized system featuring an unconventional type of mobili…
Fault-tolerant compiling of classically hard IQP circuits on hypercubes
Dominik Hangleiter, Marcin Kalinowski, Dolev Bluvstein +6
Realizing computationally complex quantum circuits in the presence of noise and imperfections is a challenging task. While fault-tolerant quantum computing provides a route to redu…
Evaluating a quantum-classical quantum Monte Carlo algorithm with Matchgate shadows
Benchen Huang, Yi-Ting Chen, Brajesh Gupt +4
Solving the electronic structure problem of molecules and solids to high accuracy is a major challenge in quantum chemistry and condensed matter physics. The rapid emergence and de…
