Quantum Sensing with Erasure Qubits

Physical Review Letters
The dominant noise in an "erasure qubit" is an erasure -- a type of error whose occurrence and location can be detected. Erasure qubits have potential to reduce the overhead associated with fault tolerance. To date, research on erasure qubits has primarily focused on quantum computing and quantum networking applications.

High‐Efficiency Quantum Defect Generation in Carbon Nanotubes via Oxygen‐Free Photochemistry

Advanced Functional Materials, EarlyView.
We show that oxygen plays an important role in quantum defect formation in carbon nanotubes and identify reaction conditions to create a range of different quantum defects for photonics and biosensing. ABSTRACT Single‐walled carbon nanotubes (SWCNTs) offer potential for a wide range of applications from optoelectronic devices to biomedical diagnostics.

Stabilization of Strongly Reduced Fe(I) Single Atom Species Coordinated in a 2D Self‐Assembled Metal–Organic Network

Advanced Functional Materials, EarlyView.
A graphene‐supported 2D metal–organic network stabilizes highly reactive Fe(I)‐N4 single sites through Co‐induced charge redistribution. Combined experiments and theory reveal Fe(I) formation, oxygen‐driven oxidation, and O2 activation mechanisms, offering a strategy to access low‐valent iron centers relevant to catalytic and biological processes ...

Arbitrary Gates on the Double Transition of NV Ground State for Low Field or High Frequency Sensing [PDF]

The NV-ERC technique for control of the NV ground state exploits the spin-1 nature of the system to best initialize the double-quantum transition. It has been proven to be a crucial control strategy for low field or high frequency sensing.

Localization-driven quantum sensing

Physical Review A
We show that the delocalization-localization transition in a quantum-many body (QMB) systems is a compelling quantum resource for achieving quantum-enhanced sensitivity in parameter estimation. We exploit the vulnerability of a near-transition QMB state against the parameter shift for devising efficient sensing tools.
