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…
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…
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…
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…
