Dynamical Decoupling of Nonclassical States in a Biased-Noise Spin Qudit
Arjen Vaartjes, Namit Anand, Rocky Y. Su +16
Encoding quantum information in -dimensional systems (qudits) with offers appealing new directions for resource-efficient quantum computing. However, protecting the cohere…
Electron readout contrast enhancement in the parallel nuclear regime of an exchange-coupled donor spin qubit system
Holly G. Stemp, Mark R. van Blankenstein, Benjamin Wilhelm +10
Recent experiments on donor-based spin qubits in silicon have leveraged the exchange interaction between electrons bound to separate donor nuclei to perform two-qubit operations. A…
Maximizing the nondemolition nature of a quantum measurement via an adaptive readout protocol
Arjen Vaartjes, Rocky Yue Su, Laura A. O'Neill +15
Quantum error correction (QEC) requires non-invasive measurements for fault tolerant quantum computing. Deviations from ideal quantum non-demolition (QND) measurements can disturb…
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…
Certifying the quantumness of a nuclear spin qudit through its uniform precession
Arjen Vaartjes, Martin Nurizzo, Lin Htoo Zaw +16
Spin precession is a textbook example of dynamics of a quantum system that exactly mimics its classical counterpart. Here we challenge this view by certifying the quantumness of ex…
Spin Qubits with Scalable milli-kelvin CMOS Control
Samuel K. Bartee, Will Gilbert, Kun Zuo +14
A key virtue of spin qubits is their sub-micron footprint, enabling a single silicon chip to host the millions of qubits required to execute useful quantum algorithms with error co…
Schrödinger cat states of a nuclear spin qudit in silicon
Xi Yu, Benjamin Wilhelm, Danielle Holmes +17
High-dimensional quantum systems are a valuable resource for quantum information processing. They can be used to encode error-correctable logical qubits, which has been demonstrate…
Real-time feedback protocols for optimizing fault-tolerant two-qubit gate fidelities in a silicon spin system
Nard Dumoulin Stuyck, Amanda E. Seedhouse, Santiago Serrano +10
Recently, several groups have demonstrated two-qubit gate fidelities in semiconductor spin qubit systems above 99%. Achieving this regime of fault-tolerant compatible high fideliti…
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…
Wavelet correlation noise analysis for qubit operation variable time series

M. A. Fogarty, K. W. Chan, B. Hensen +10
Silicon quantum dot spin qubits provide a promising platform for large-scale quantum computation because of their compatibility with conventional CMOS manufacturing and the long co…
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…
Violation of a Leggett-Garg inequality with ideal non-invasive measurements
George C. Knee, Stephanie Simmons, Erik M. Gauger +9
The quantum superposition principle states that an entity can exist in two different states simultaneously, counter to our 'classical' intuition. Is it possible to understand a giv…
