Roadmap to fault tolerant quantum computation using topological qubit arrays
David Aasen, Morteza Aghaee, Zulfi Alam +179
We describe a concrete device roadmap towards a fault-tolerant quantum computing architecture based on noise-resilient, topologically protected Majorana-based qubits. Our roadmap e…
A Cryogenic Interface for Controlling Many Qubits
S. J. Pauka, K. Das, R. Kalra +9
A scaled-up quantum computer will require a highly efficient control interface that autonomously manipulates and reads out large numbers of qubits, which for solid-state implementa…
Coherent control via weak measurements in P single-atom electron and nuclear spin qubits
J. T. Muhonen, J. P. Dehollain, A. Laucht +8
The understanding of weak measurements and interaction-free measurements has greatly expanded the conceptual and experimental toolbox to explore the quantum world. Here we demonstr…
A single-atom quantum memory in silicon
S. Freer, S. Simmons, A. Laucht +10
Long coherence times and fast gate operations are desirable but often conflicting requirements for physical qubits. This conflict can be resolved by resorting to fast qubits for op…
Quantifying the quantum gate fidelity of single-atom spin qubits in silicon by randomized benchmarking
J. T. Muhonen, A. Laucht, S. Simmons +9
Building upon the demonstration of coherent control and single-shot readout of the electron and nuclear spins of individual 31-P atoms in silicon, we present here a systematic expe…
High-fidelity adiabatic inversion of a electron spin qubit in natural silicon
Arne Laucht, Rachpon Kalra, Juha T. Muhonen +7
The main limitation to the high-fidelity quantum control of spins in semiconductors is the presence of strongly fluctuating fields arising from the nuclear spin bath of the host ma…
Robust two-qubit gates for donors in silicon controlled by hyperfine interactions
Rachpon Kalra, Arne Laucht, Charles Hill +1
We present two strategies for performing two-qubit operations on the electron spins of an exchange-coupled pair of phosphorus donors in silicon, using the ability to set the donor…
