One-clean-qubit spectroscopy of simulated Kitaev chains
Z. M. McIntyre, Daniel Loss
Spin qubits in gate-defined quantum dots provide a highly programmable platform for simulating condensed-matter phenomena. In this work, we introduce a digital-analog quantum simul…
Spin Kerr-cat qubits
Z. M. McIntyre, Daniel Loss
The use of noise-robust qubit encodings provides a way of extending the lifetime of quantum information at the hardware level. In this work, we introduce the spin Kerr-cat encoding…
Theory of spin qubits and the path to scalability
Z. M. McIntyre, Abhikbrata Sarkar, Daniel Loss
Spin qubits have emerged as a leading platform for quantum information processing due to their long coherence times, small footprint, and compatibility with the existing semiconduc…
Heisenberg-limited metrology from the quantum-quench dynamics of an anisotropic ferromagnet
Z. M. McIntyre, Ji Zou, Jelena Klinovaja +1
The emerging field of quantum magnonics seeks to understand and harness the quantum properties of magnons -- quantized collective spin excitations in magnets. Squeezed magnon state…
Extended Coherent States
Z. M. McIntyre, A. Kasman, R. Milson
Using the formalism of Maya diagrams and ladder operators, we describe the algebra of annihilating operators for the class of rational extensions of the harmonic oscillator. This a…
Loss-tolerant parallelized Bell-state generation with a hybrid cat qudit
Z. M. McIntyre, W. A. Coish
Having multiple Bell pairs shared by distant quantum registers provides a key resource for both quantum networks and distributed quantum computing. In this paper, we present a prot…
Quantum information processing in modular cavity QED architectures
Z. M. McIntyre
This thesis contains a collection of articles exploring various aspects of quantum information processing with cavity quantum electrodynamics (QED), starting with qubit noise spect…
Protocols for inter-module two-qubit gates mediated by time-bin encoded photons
Z. M. McIntyre, W. A. Coish
As quantum devices scale to larger numbers of qubits, entangling gates between distant stationary qubits will help provide flexible, long-range connectivity in modular architecture…
Dimensionality reduction for closed-loop quantum gate calibration
Emma Berger, Vivek Maurya, Z. M. McIntyre +3
Numerical gate design typically makes use of high-dimensional parameterizations enabling sophisticated, highly expressive control pulses. Developing efficient experimental calibrat…
Homodyne detection is optimal for quantum interferometry with path-entangled coherent states
Z. M. McIntyre, W. A. Coish
We present measurement schemes that do not rely on photon-number resolving detectors, but that are nevertheless optimal for estimating a differential phase shift in interferometry…
Flying-cat parity checks for quantum error correction
Z. M. McIntyre, W. A. Coish
Long range, multi-qubit parity checks have applications in both quantum error correction and measurement-based entanglement generation. Such parity checks could be performed using…
A photonic which-path entangler based on longitudinal cavity-qubit coupling
Z. M. McIntyre, W. A. Coish
We show that a modulated longitudinal cavity-qubit coupling can be used to control the path taken by a multiphoton coherent-state wavepacket conditioned on the state of a qubit, re…
Non-Markovian transient spectroscopy in cavity QED
Z. McIntyre, W. A. Coish
We theoretically analyze measurements of the transient field leaving a cavity as a tool for studying non-Markovian dynamics in cavity quantum electrodynamics (QED). Combined with a…
Constructing Coherent States for the Rational Extensions of the Harmonic Oscillator Potential
Zoé McIntyre, Robert Milson
Using the formalism of Maya diagrams and ladder operators, we describe the algebra of annihilating operators for the class of rational extensions of the harmonic oscillators. This…
Ladder operators and rational extensions
David Gomez-Ullate, Yves Grandati, Zoe McIntyre +1
This note presents the classification of ladder operators corresponding to the class of rational extensions of the harmonic oscillator. We show that it is natural to endow the clas…
