“…Monitoring minute changes in acceleration can provide information about the terrain and the surrounding environment. Recently, quantum kinematics sensors have emerged as a powerful quantum system that combines the outstanding consistency characteristics and monitoring mechanisms of atomic systems with the tiny dimensions and construction capabilities of solid-state equipment [66,67,68]. According to the review results, the accuracy of quantum kinematics sensing measurements of high-precision rotation and acceleration has improved significantly compared to that of classical systems.…”

The current rise of quantum technology is compelled by quantum sensing research. Thousands of research labs are developing and testing a broad range of sensor prototypes. However, there is a lack of knowledge about specific applications and real-world use cases where the benefits of these sensors will be most pronounced. This study presents a comprehensive review of quantum sensing state-of-practice. It also provides a detailed analysis of how quantum sensing overcomes the existing limitations of sensordriven systems' precision and performance. Based on the review of over 500 quantum sensor prototype reports, we determined four groups of quantum sensors and discussed their readiness for commercial usage. We concluded that quantum magnetometry and quantum optics are the most advanced sensing technologies with empirically proven results. In turn, quantum timing and kinetics are still in the early stages of practical validation. In addition, we defined four systems domains in which quantum sensors offer a solution for existing limitations of conventional sensing technologies. These domains are 1) GPS-free positioning and navigating services, 2) time-based operations, 3) topological visibility, and 4) environment detection, prediction, and modeling. Finally, we discussed the current constraints of quantum sensing technologies and offered directions for future research.

“…Finally, we note that the fault-tolerant protocol we have developed leverages variable connectivity of the physical qubits and exhibits relatively high pseudothresholds for certain quantum computing tasks, making it particularly suitable for other platforms with high qubit connectivity, such as neutral atoms (18,19) and nitrogenvacancy (NV)-based networks (20,21). A similar idea has recently been proposed to implement quantum low-density parity-check codes (qLDPCs) using reconfigurable atom arrays (18).…”

Fault-tolerant operations based on stabilizer codes are the state of the art in suppressing error rates in quantum computations. Most such codes do not permit a straightforward implementation of non-Clifford logical operations, which are necessary to define a universal gate set. As a result, implementations of these operations must use either error-correcting codes with more complicated error correction procedures or gate teleportation and magic states, which are prepared at the logical level, increasing overhead to a degree that precludes near-term implementation. Here, we implement a small quantum algorithm, one-qubit addition, fault-tolerantly on a trapped-ion quantum computer, using the [[ 8 , 3 , 2 ]] color code. By removing unnecessary error correction circuits and using low-overhead techniques for fault-tolerant preparation and measurement, we reduce the number of error-prone two-qubit gates and measurements to 36. We observe arithmetic errors with a rate of ∼1.1 × 10 −3 for the fault-tolerant circuit and ∼9.5 × 10 −3 for the unencoded circuit.

Research directed toward the goal of molecular gyroscopes since the coverage of a previous review (2002) is described. Such species are a subclass of molecular rotors, which are comprised of rotators and stators. Major categories include (1) systems in which a rotator is embedded in a cage-like stator reminiscent of mechanical toy gyroscopes and (2) molecules that have been engineered to crystallize with parallel rotators and voids or other features that enable the rotator to rotate in the solid state (amphidynamic crystals). Particular attention is given to structural data and strategies for the minimization of rotational barriers. Synthetic routes are also described. Some allied types of molecules and supramolecular assemblies are also treated.
