A Molecular Approach to Quantum Sensing

Abstract: The second quantum revolution hinges on the creation of materials that unite atomic structural precision with electronic and structural tunability. A molecular approach to quantum information science (QIS) promises to enable the bottom-up creation of quantum systems. Within the broad reach of QIS, which spans fields ranging from quantum computation to quantum communication, we will focus on quantum sensing. Quantum sensing harnesses quantum control to interrogate the world around us. A broadly applicable class… Show more

“…[ 3 , 4 , 5 , 6 ] Recently, titanium cations have been also proposed as qubits [7] or for quantum sensing devices. [ 8 , 9 ] In many cases qubit molecules show field‐induced slow spin relaxation, where a small external field suppresses quantum tunnelling of magnetization (QTM) relaxation and the molecular‐based material shows slow spin relaxation.…”

“…Our results pave the way for improved resolution and broad applications of nano-NMR with NV centres. The power-law scaling of correlations which originates in the dipole-dipole interaction between sensor and sample is key to this result, extending the applicability of our results to any quantum sensor based on this interaction, such as Rydberg atoms, squid based sensors, molecular quantum sensors, or alternative colour centres such as silicon carbide [40]. In addition, the ability to measure accurately correlations of nano-sized fluid samples, opens the door to study flow properties at these scales.…”

“…However, as NMR technology advances with techniques like hyper-polarization [80], multi-dimensional methods [81], spatial resolution [82], and zero-field techniques [83], we appear to be accessing more and more pure quantum states with increasing control [84]. In addition the design of more advanced molecular quantum sensors is an active research area [85]. With sufficient advances in transduction techniques and developments in quantum error correction, it may become possible to load data from molecules directly into quantum computers, and perform manipulations that are provably challenging for a classical device even with unbounded compute time to replicate, due to the query separations we mention above.…”
