Roadmap on Nanoscale Magnetic Resonance Imaging
Raffi Budakian, Amit Finkler, Alexander Eichler +22
The field of nanoscale magnetic resonance imaging (NanoMRI) was started 30 years ago. It was motivated by the desire to image single molecules and molecular assemblies, such as pro…
"Galton board" nuclear hyperpolarization
Moniish Elanchezhian, Arjun Pillai, Teemu Virtanen +1
We consider the problem of determining the spectrum of an electronic spin via polarization transfer to coupled nuclear spins and their subsequent readout. This suggests application…
Novel Trotter formulas for digital quantum simulation
Yi-Xiang Liu, Jordan Hines, Zhi Li +2
Quantum simulation promises to address many challenges in fields ranging from quantum chemistry to material science, and high-energy physics, and could be implemented in noisy inte…
Cross-sensor feedback stabilization of an emulated quantum spin gyroscope
Jean-Christophe Jaskula, Kasturi Saha, Ashok Ajoy +3
Quantum sensors, such as the Nitrogen Vacancy (NV) color center in diamond, are known for their exquisite sensitivity, but their performance over time are subject to degradation by…
Selective decoupling and Hamiltonian engineering in dipolar spin networks
Ashok Ajoy, Ulf Bissbort, Dario Poletti +1
We present a protocol to selectively decouple, recouple, and engineer effective couplings in mesoscopic dipolar spin networks. In particular, we develop a versatile protocol that r…
A bright nanowire single photon source based on SiV centers in diamond
L. Marseglia, K. Saha, A. Ajoy +8
The practical implementation of many quantum technologies relies on the development of robust and bright single photon sources that operate at room temperature. The negatively char…

Recent advances in engineering and control of nanoscale quantum sensors have opened new paradigms in precision metrology. Unfortunately, hardware restrictions often limit the senso…
Atomic-scale nuclear spin imaging using quantum-assisted sensors in diamond
Ashok Ajoy, Ulf Bissbort, Mikhail D. Lukin +2
Nuclear spin imaging at the atomic level is essential for the understanding of fundamental biological phenomena and for applications such as drug discovery. The advent of novel nan…
Decay of spin coherences in one-dimensional spin systems
Gurneet Kaur, Ashok Ajoy, Paola Cappellaro
Strategies to protect multi-qubit states against decoherence are difficult to formulate because of their complex many-body dynamics. A better knowledge of the decay dynamics would…
Quantum simulation via filtered Hamiltonian engineering: application to perfect quantum transport in spin networks
Ashok Ajoy, Paola Cappellaro
We propose a method for Hamiltonian engineering in quantum information processing architectures that requires no local control, but only relies on collective qubit rotations and fi…
