An ultra-stable 1.5 tesla permanent magnet assembly for qubit experiments at cryogenic temperatures
C. Adambukulam, V. K. Sewani, H. G. Stemp +4
Magnetic fields are a standard tool in the toolbox of every physicist, and are required for the characterization of materials, as well as the polarization of spins in nuclear magne…
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…
Coherent electrical control of a single high-spin nucleus in silicon
Serwan Asaad, Vincent Mourik, Benjamin Joecker +12
Nuclear spins are highly coherent quantum objects. In large ensembles, their control and detection via magnetic resonance is widely exploited, e.g. in chemistry, medicine, material…
