Tracking spin qubit frequency variations over 912 days
Kenji Capannelli, Brennan Undseth, Irene Fernández de Fuentes +9
Solid-state qubits are sensitive to their microscopic environment, causing the qubit properties to fluctuate on a wide range of timescales. The sub-Hz end of the spectrum is usuall…
Scalable entanglement of nuclear spins mediated by electron exchange
Holly G. Stemp, Mark R. van Blankenstein, Serwan Asaad +11
The use of nuclear spins for quantum computation is limited by the difficulty in creating genuine quantum entanglement between distant nuclei. Current demonstrations of nuclear ent…

Intels efforts to build a practical quantum computer are focused on developing a scalable spin-qubit platform leveraging industrial high-volume semiconductor manufacturing expertis…
Probing single electrons across 300 mm spin qubit wafers
Samuel Neyens, Otto K. Zietz, Thomas F. Watson +27
Building a fault-tolerant quantum computer will require vast numbers of physical qubits. For qubit technologies based on solid state electronic devices, integrating millions of qub…
Hotter is easier: unexpected temperature dependence of spin qubit frequencies
Brennan Undseth, Oriol Pietx-Casas, Eline Raymenants +13
As spin-based quantum processors grow in size and complexity, maintaining high fidelities and minimizing crosstalk will be essential for the successful implementation of quantum al…
Universal control of a six-qubit quantum processor in silicon
Stephan G. J. Philips, Mateusz T. Mądzik, Sergey V. Amitonov +12
Future quantum computers capable of solving relevant problems will require a large number of qubits that can be operated reliably. However, the requirements of having a large qubit…
Atomic fluctuations lifting the energy degeneracy in Si/SiGe quantum dots
Brian Paquelet Wuetz, Merritt P. Losert, Sebastian Koelling +16
Electron spins in Si/SiGe quantum wells suffer from nearly degenerate conduction band valleys, which compete with the spin degree of freedom in the formation of qubits. Despite att…
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…
An ultra-stable 1.5 tesla permanent magnet assembly for qubit experiments at cryogenic temperatures

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…
