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…
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…
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…
Combining multiplexed gate-based readout and isolated CMOS quantum dot arrays
Pierre Hamonic, Martin Nurizzo, Jayshankar Nath +15
Semiconductor quantum dot arrays are a promising platform to perform spin-based error-corrected quantum computation with large numbers of qubits. However, due to the diverging numb…
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…
Electrical manipulation of a single electron spin in CMOS with micromagnet and spin-valley coupling
Bernhard Klemt, Victor El-Homsy, Martin Nurizzo +16
For semiconductor spin qubits, complementary-metal-oxide-semiconductor (CMOS) technology is the ideal candidate for reliable and scalable fabrication. Making the direct leap from a…
Complete readout of two-electron spin states in a double quantum dot
Martin Nurizzo, Baptiste Jadot, Pierre-André Mortemousque +9
We propose and demonstrate complete spin state readout of a two-electron system in a double quantum dot probed by an electrometer. The protocol is based on repetitive single shot m…
Parity and singlet-triplet high fidelity readout in a silicon double quantum dot at 0.5 K
David J. Niegemann, Victor El-Homsy, Baptiste Jadot +14
We demonstrate singlet-triplet readout and parity readout allowing to distinguish T0 and the polarized triplet states. We achieve high fidelity spin readout with an average fidelit…
Controlled quantum dot array segmentation via a highly tunable interdot tunnel coupling
Martin Nurizzo, Baptiste Jadot, Pierre-André Mortemousque +8
Recent demonstrations using electron spins stored in quantum dots array as qubits are promising for developing a scalable quantum computing platform. An ongoing effort is therefore…
