The giant acoustic atom -- a single quantum system with a deterministic time delay
Lingzhen Guo, Arne Grimsmo, Anton Frisk Kockum +2
We investigate the quantum dynamics of a single transmon qubit coupled to surface acoustic waves (SAWs) via two distant connection points. Since the acoustic speed is five orders o…
Resolving magnon number states in quantum magnonics
Dany Lachance-Quirion, Yutaka Tabuchi, Seiichiro Ishino +4
Collective excitation modes in solid state systems play a central role in circuit quantum electrodynamics, cavity optomechanics, and quantum magnonics. In the latter, quanta of col…
Quantum annealing with a network of all-to-all connected, two-photon driven Kerr nonlinear oscillators
Shruti Puri, Christian Kraglund Andersen, Arne L. Grimsmo +1
Quantum annealing aims to solve combinatorial optimization problems mapped on to Ising interactions between quantum spins. A critical factor that limits the success of a quantum an…
Resonator reset in circuit QED by optimal control for large open quantum systems
Samuel Boutin, Christian Kraglund Andersen, Jayameenakshi Venkatraman +2
We study an implementation of the open GRAPE (Gradient Ascent Pulse Engineering) algorithm well suited for large open quantum systems. While typical implementations of optimal cont…
Squeezing and quantum state engineering with Josephson traveling wave amplifiers
Arne L. Grimsmo, Alexandre Blais
We develop a quantum theory describing the input-output properties of Josephson traveling wave parametric amplifiers. This allows us to show how such a device can be used as a sour…
Ultrastrong coupling dynamics with a transmon qubit
Christian Kraglund Andersen, Alexandre Blais
The interaction of light and matter is often described by the exchange of single excitations. When the coupling strength is a significant fraction of the system frequencies, the nu…
Foliated Quantum Codes
A. Bolt, G. Duclos-Cianci, D. Poulin +1
We show how to construct a large class of quantum error correcting codes, known as CSS codes, from highly entangled cluster states. This becomes a primitive in a protocol that foli…
Tensor-Network Simulations of the Surface Code under Realistic Noise
Andrew S. Darmawan, David Poulin
The surface code is a many-body quantum system, and simulating it in generic conditions is computationally hard. While the surface code is believed to have a high threshold, the nu…
Fault-Tolerant Quantum Error Correction for non-Abelian Anyons
Guillaume Dauphinais, David Poulin
While topological quantum computation is intrinsically fault-tolerant at zero temperature, it loses its topological protection at any finite temperature. We present a scheme to pro…
Representation and design of wavelets using unitary circuits
Glen Evenbly, Steven R. White
The representation of discrete, compact wavelet transformations (WTs) as circuits of local unitary gates is discussed. We employ a similar formalism as used in the multi-scale repr…
Engineering the quantum states of light in a Kerr-nonlinear resonator by two-photon driving
Shruti Puri, Samuel Boutin, Alexandre Blais
Cat states of the microwave field stored in high-Q resonators show great promise for robust encoding and manipulation of quantum information. Here we propose an approach to efficie…
Physical Resources for Quantum-enhanced Phase Estimation
Jaspreet Sahota, Nicolás Quesada, Daniel F. V. James
We study the role of quantum entanglement (particle entanglement and mode entanglement) in optical phase estimation by employing the first and second quantization formalisms of qua…
Fast and High-Fidelity Entangling Gate through Parametrically Modulated Longitudinal Coupling
Baptiste Royer, Arne L. Grimsmo, Nicolas Didier +1
We investigate an approach to universal quantum computation based on the modulation of longitudinal qubit-oscillator coupling. We show how to realize a controlled-phase gate by sim…
Hamiltonian engineering for robust quantum state transfer and qubit readout in cavity QED
Félix Beaudoin, Alexandre Blais, W. A. Coish
Quantum state transfer into a memory, state shuttling over long distances via a quantum bus, and high-fidelity readout are important tasks for quantum technology. Realizing these t…
Resonance fluorescence from an artificial atom in squeezed vacuum
D. M. Toyli, A. W. Eddins, S. Boutin +6
We present an experimental realization of resonance fluorescence in squeezed vacuum. We strongly couple microwave-frequency squeezed light to a superconducting artificial atom and…
High-fidelity resonator-induced phase gate with single-mode squeezing
Shruti Puri, Alexandre Blais
We propose to increase the fidelity of two-qubit resonator-induced phase gates in circuit QED by the use of narrowband single-mode squeezed drive. We show that there exists an opti…
