Unleashing the potential of qubits, one molecule at a time

Hosage of Qubits is very difficult. For example, two of the most common species of the wrong Qubits, which are often made of delicate aluminum layers, and the besieged Qubits Ion, which uses energy levels for ion electrons to represent them 1sand 0S – It should remain at temperatures approaching absolute scratch (-273 ° C). Keeping special refrigerators to keep them cold is expensive and difficult. While the researchers have made great progress recently, it was historically difficult to connect both types of Qubits to larger systems.

Occupied to explore the Qubits molecular capabilities, Freedman rejected a unique approach “from bottom up” to create them: it designs new particles with specific quantitative properties to serve as a target Qubits for individual applications. Instead of focusing on the general target such as maximizing the time of cohesion (how much time Qubit can maintain its quantitative condition), you start asking the necessary types of properties, for example, a sensor aimed at measuring biological phenomena at the molecular level. Then she and her team began creating molecules with these characteristics and are suitable for the environment that will be used.

Made of a central mineral atom surrounded by hydrocarbon atoms, Qubits molecularly stored information in Tador. The encrypted information is later translated into photons, from which the “reading” of information is emitted. These Qubits can be adjusted with the resolution of the laser – imagine the radio telephone – by adjusting the strength of the links, or links, and linking hydrocarbons to the mineral corn. These links behave like small tuning chocolate. By adjusting their strength, researchers can accurately control Qubit and the wavelength of the emitted photons. This light emitted to provide information about the atomic levels of electrical or magnetic fields can be used.

While many researchers are eager to build a reliable and developed quantitative computers, Friedman and their group devotes most of their attention to developing particles dedicated to quantum sensors. These sound sensors contain molecules in a balanced state that is so accurate that the very small changes in their environments confuse them, causing them to empty them differently. For example, one Qubit can be dedicated to the Freedman Laboratory, made of chrome atom surrounded by four hydrocarbon particles, so that small changes in the strength of the magnetic field near its light emissions in a certain way.

One of the main benefit of using these molecules to sensing is that they are small enough – just a nanometer or wide – to get very close to the thing they feel. This can provide an unprecedented level of accuracy when measuring something like the surface magnetic magnetic materials, because the strength of the magnetic field decomposes the distance. “The molecular sensor may not be more accurate by its nature than the identical quantum sensor,” said Friedman, but if you can lose the size of the distance, this can give us a lot of information. ” The ability of quantum sensors to discover electrical or magnetic changes can be at the atomic level and make unusual accurate measurements useful in many areas, such as environmental monitoring, medical diagnoses, geographical center, and more.

When designing molecules to serve as quantum sensors, the Freedman group is also in the way it can be expected in a specific sensor environment. The creation of a water sensor, for example, requires a compatible molecule with water, and a sensor for use at very low temperatures requires improved molecules for a good cold performance. Through the engineering molecules for different uses, Freedman LAB aims to make quantum technology more diverse and widely adaptable.

Embrace specializations

While Friedman and her group focus on the very specific work of designing custom molecules, they fully realize that taking advantage of the power of quantum science depends on collective efforts of scientists in various fields.

“The quantum is a wide and homogeneous field,” she says. She believes that attempts to define her with the harm of collective research – and scientists must welcome cooperation when research leads them beyond their field. Even in the direct scenario apparently to use a quantum computer to solve the chemistry problem, you will need a physicist to write quantum algorithm, engineers and material scientists to build a computer, and chemists to determine the problem and determine how to solve the quantum computer.
