Approaching the Fundamental Limit of Single-Shot Qubit Frequency Tracking with an Adiabatic Tangentially-Modulated Pulse
Itamar Oren, Luke I. Dyer, Gerardo A. Paz-Silva +1
Understanding and mitigating noise in two level quantum systems is essential for achieving high fidelity qubit control. Conventional frequency tracking techniques, such as Ramsey i…
Multi-Qubit Entanglement of Unit Cell Pairs in SiMOS
Cameron Jones, Jonathan Y. Huang, Santiago Serrano +13
Spin qubits in silicon-MOS (SiMOS) quantum dots have recently demonstrated compatibility with existing industry standard CMOS fabrication techniques. These devices have routinely a…
Control-centric quantum noise spectroscopy of time-ordered polyspectra
Kaiah Steven, Elliot Coupe, Qi Yu +1
Precise environmental-noise characterisation in open quantum systems is a key step toward high-fidelity quantum control and targeted decoherence suppression in computing and sensin…
Precision bounds for frequency estimation under collective dephasing and open-loop control
Francisco Riberi, Gerardo Paz-Silva, Lorenza Viola
Dephasing noise is a ubiquitous source of decoherence in current atomic sensors. We address the problem of entanglement-assisted frequency estimation subject to classical dephasing…
Mid-circuit logic executed in the qubit layer of a quantum processor
Cameron Jones, Piper Wysocki, MengKe Feng +16
Practical quantum computers need to continuously exchange data between classical and quantum subsystems during a computation. Mid-circuit measurements of a qubits state are transfe…
Quantum Engineering of Qudits with Interpretable Machine Learning
Yule Mayevsky, Akram Youssry, Ritik Sareen +2
Higher-dimensional quantum systems (qudits) offer advantages in information encoding, error resilience, and compact gate implementations, and naturally arise in platforms such as s…
