Tomography of entangling two-qubit logic operations in exchange-coupled donor electron spin qubits
Holly G. Stemp, Serwan Asaad, Mark R. van Blankenstein +19
Scalable quantum processors require high-fidelity universal quantum logic operations in a manufacturable physical platform. Donors in silicon provide atomic size, excellent quantum…
High-fidelity operation and algorithmic initialisation of spin qubits above one kelvin
Jonathan Y. Huang, Rocky Y. Su, Wee Han Lim +23
The encoding of qubits in semiconductor spin carriers has been recognised as a promising approach to a commercial quantum computer that can be lithographically produced and integra…
Error channels in quantum nondemolition measurements on spin systems
Benjamin Joecker, Holly G. Stemp, Irene Fernández de Fuentes +2
Quantum nondemolition (QND) measurements are a precious resource for quantum information processing. Repetitive QND measurements can boost the fidelity of qubit preparation and mea…
Navigating the 16-dimensional Hilbert space of a high-spin donor qudit with electric and magnetic fields
Irene Fernández de Fuentes, Tim Botzem, Mark A. I. Johnson +11
Efficient scaling and flexible control are key aspects of useful quantum computing hardware. Spins in semiconductors combine quantum information processing with electrons, holes or…
Single-Step Parity Check Gate Set for Quantum Error Correction
Gözde Üstün, Andrea Morello, Simon Devitt
A key requirement for an effective Quantum Error Correction (QEC) scheme is that the physical qubits have error rates below a certain threshold. The value of this threshold depends…
Robust Macroscopic Schrödinger's Cat on a Nucleus
Pragati Gupta, Arjen Vaartjes, Xi Yu +2
We propose a scheme to generate spin cat states, i.e., superpositions of maximally separated quasiclassical states on a single high-dimensional nuclear spin in a solid-state device…
Assessment of error variation in high-fidelity two-qubit gates in silicon
Tuomo Tanttu, Wee Han Lim, Jonathan Y. Huang +24
Achieving high-fidelity entangling operations between qubits consistently is essential for the performance of multi-qubit systems and is a crucial factor in achieving fault-toleran…
