An electrically-driven single-atom `flip-flop' qubit
Rostyslav Savytskyy, Tim Botzem, Irene Fernandez de Fuentes +9
The spins of atoms and atom-like systems are among the most coherent objects in which to store quantum information. However, the need to address them using oscillating magnetic fie…
Beating the thermal limit of qubit initialization with a Bayesian Maxwell's demon
Mark A. I. Johnson, Mateusz T. Mądzik, Fay E. Hudson +5
Fault-tolerant quantum computing requires initializing the quantum register in a well-defined fiducial state. In solid-state systems, this is typically achieved through thermalizat…
Precision tomography of a three-qubit donor quantum processor in silicon
Mateusz T. Mądzik, Serwan Asaad, Akram Youssry +17
Nuclear spins were among the first physical platforms to be considered for quantum information processing, because of their exceptional quantum coherence and atomic-scale footprint…
Donor spins in silicon for quantum technologies
Andrea Morello, Jarryd J. Pla, Patrice Bertet +1
Dopant atoms are ubiquitous in semiconductor technologies, providing the tailored electronic properties that underpin the modern digital information era. Harnessing the quantum nat…
Conditional quantum operation of two exchange-coupled single-donor spin qubits in a MOS-compatible silicon device
Mateusz T. Mądzik, Arne Laucht, Fay E. Hudson +6
Silicon nanoelectronic devices can host single-qubit quantum logic operations with fidelity better than 99.9%. For the spins of an electron bound to a single donor atom, introduced…
Controllable freezing of the nuclear spin bath in a single-atom spin qubit
Mateusz T. Mądzik, Thaddeus D. Ladd, Fay E. Hudson +8
The quantum coherence and gate fidelity of electron spin qubits in semiconductors is often limited by noise arising from coupling to a bath of nuclear spins. Isotopic enrichment of…
