About us

We are a Technology Company enjoying access to highest-level scientific and engineering expertise, and World-class experimental and testing facilities.

The goal of our technology,

is to resolve an issue encountered with many modern navigation devices – their dependence on GPS.

The idea of combining MEMS(1) gyros with GNSS(2) receivers involved the use of external measurements from the GNSS with a goal of limiting error accummulation in the MEMS gyros' data. However, GNSS availability is limited indoors, under water/ground, and in the areas with high concentration of tall buildings. Additionally, devices capable of introducing errors into GNSS signals are now widly used in many states. The proposed quantum gyro can help address this issue, as its Bias Drift is almost zero, which reduces its reliance on external measurements.

Technology in detail

At Quantum Sensorix

our goal is the development of a solid-state, compact, diamond-based gyro competing with best MEMS devices in terms of their sensitivity and significantly surpassing those with respect to bias stability.

A diamond sample hosting nitrogen-vacancy (NV) color centers – the most common color centers in diamond - will be used as the rotation-sensing element. Artificial diamonds allow for precisely controlled concentration of the NV-centers, offering significant flexibility in sensor systems design and development.

A Nitrogen-Vacancy center in diamond

Electronic and nuclear spins can assume various spatial orientations.

The sensing mechanism

is based on the so-called “spin” – inherent, ever-present rotation of elementary particles. Much like a fast-rotating top, elementary particles – electrons and nucleons – preserve their orientation in space even when affixed to a moving platform, thus acting like natural gyros. The NV-centers exhibit two intrinsic spins – electronic and nuclear (schematically shown on the left) - both of which can be used in rotation sensor design.

The two-spin system

possesses unique and useful properties. The electron spin of an NV-center is readily accessible. Its state can be relatively easily prepared and read out by its own florescence, as illustrated in the picture on the right. The nuclear spin is somewhat hidden and difficult to access. Although both spins are sensitive to rotation, the nuclear spin is more stable due to its weaker interaction with the external factors. As a result, despite of its reduced accessibility, nuclear spin proves a better candidate to serve as the main sensing element of a rotation sensor.

The electronic spin state can be easily prepared and read out optically.

Transfer of quantum state information from electronic to nuclear spin.

In contrast to the electron spin,

the nuclear spin is light-insensitive, and it has longer coherence time, allowing for signal accumulation over longer time spans. These properties make nuclear spin more difficult to manage. Fortunately, nuclear spin can be effectively manipulated via its interaction with its electronic counterpart. Being located in close proximity to each other - inside the same NV-center - the two spins strongly interact. This gives one an opportunity, with help of a radio-frequency pulse, to map a prepared electronic spin state onto that of the nuclear spin (see the picture on the right), and, conversely, to map a nuclear spin state onto that of the electronic spin. The latter can then be easily read out by measuring the frequency of electron florescence.

Since it is possible to independently work with the electron and nuclear spins, one can measure any number of extraneous factors such as magnetic field, temperature and pressure and use results to compensate useful sensor signal, thus yielding self-contained, self-locked sensor build on a single diamond substrate.

The above self-calibration is a unique feature of the proposed device. The electron and nuclear spins are all exactly the same in nature. Their response to a frame rotation and applied magnetic field does not change, thus excluding any intrinsic bias drift. The measurement of the sensor’s rotation speed is carried out by registering the change in the nuclear spin precession frequency and relaying mostly on physical constants, rather than man-made properties used in MEMS devices.

Since physical constants have the same values in any diamond sample, the is no fundamental drift of the sensor bias line. And although there are technical drifts, such as those caused by external magnetic fields, those can be fully controlled within sensor itself, obviating the need for external calibration.

The functional sensitivity of the proposed sensor depends strongly on the number of color centers embedded in the diamond host and on the coherence properties of these color centers. It is also influenced by the presence of other impurities that may affect signal collection efficiency. With today’s diamond-growing technology and need for miniaturization and limited energy consumption, the sensor can easily target sensitivity of the tactical grade navigational sensors plus offer additional sensing functions such as electric & magnetic field, temperature and pressure sensing.

Thus, quantum based, highly sensitive measurement devises will soon become prevalent in such industries as health care, gaming, transportation and defense by providing ability to remotely read peoples’ thoughts, measure temperature in extreme environments, guide any vehicle without the need for the satellite based nav aid and many more applications for the future needs of industrial growth. In addition, the same principal of spin interactions between the electron and the nucleus may be used in the future to store and transfer quantum bit data opening up the field of the research into a much larger market.

In conclusion, our team has already developed a working prototype with the sensitivity of average MEMS gyro sensors with a benefit of nearly zero drift bias. We expect the proposed R&D effort to yield a microchip size, low power consumption, self-contained, self-locked diamond-based rotation sensor with nearly zero bias drift and sensitivity rivaling that of the best MEMS gyros capable of withstanding harsh environments.
