Aboard the International Space Station, there's a compact lab about the size of a small refrigerator that makes some of the coldest stuff in the universe. It's called the Cold Atom Lab, and for some time, scientists have been using this chamber to research the strange quantum properties of atoms in microgravity. But on Wednesday (Nov. 15), they announced they've reached a milestone. Operated remotely by a team with NASA's Jet Propulsion Laboratory (JPL) in California, the Cold Atom Lab officially generated a quantum gas containing two species of atoms. This could ultimately open the door for totally new space-based experiments in quantum chemistry. When thinking about states of matter, gases, liquids, solids and plasmas are the four well known ones — but there's also an exotic fifth state of matter, the Bose-Einstein condensate, that was first discovered in the 1990s. This state hasn't been found in nature, but scientists can create it. Bose-Einstein condensates are generated in ultracold labs like the Cold Atom Lab, where lasers or magnets help chill a cloud of atoms close to absolute zero, or -459 degrees Fahrenheit (-273 degrees Celsius). That's the coldest temperature possible in the universe. In this state, atoms slow down, their edges blend together, and scientists can observe quantum effects that are usually very hard to investigate.

Weird quantum phenomena like quantum tunnelling, superposition, and entanglement become more evident as the size of current technology decreases down to the nanoscale.

An open quantum system and a detector with a limited bandwidth are used to illustrate a typical measurement and feedback configuration.

An arbitrary system observable is continually measured by the detector. Measurement backaction is determined by measurement strength.

Utilizing the measurement result D, continuous feedback is used to regulate the system's Liouville superoperator L(D).

The time traces show the trajectories of the measurement record D(t) and the system state S(t):

This ushers in a new age of quantum technology that allows for the exploitation of quantum effects.

A pacemaker is a prime example of a common technology that often employs feedback control since it must continuously monitor the user's heartbeat and only apply electrical impulses to regulate it when necessary.

However, quantum feedback control is still not fully understood by physicists.

The "master equation" that scientists have now created will aid engineers in comprehending feedback at the quantum scale.

Physical Review Letters, a publication, has published its findings. According to co-author Björn Annby-Andersson, a quantum physicist at Sweden's Lund University, "It is crucial to investigate how feedback control can be used in quantum technologies in order to develop efficient and quick methods for controlling quantum systems, so that they can be steered in real time and with high precision."

Quantum error correction is an illustration of an important feedback-control procedure in quantum computing.

A quantum computer stores information on actual qubits, which might be, for example, atoms or light photons.

However, due to the qubits' delicate quantum characteristics, it is possible that if they are jarred by vibrations or fluctuating electromagnetic fields, the encoded information will be lost.

Therefore, physicists must be able to recognize and fix such mistakes, for example, by using feedback control.

By monitoring the qubits' state and using feedback to rectify any deviations from expectations that are found, this error correction may be put into practice.

However, because of the fragility that physicists are attempting to counteract, feedback control at the quantum level poses special difficulties.

Due to its fragile nature, the system might be destroyed even by the feedback process.

According to Annby-Andersson, "it is crucial to only interact weakly with the measured system, keeping the qualities we wish to exploit."

Therefore, it is crucial to build a complete theoretical knowledge of quantum feedback control in order to determine its basic bounds.

However, the majority of the theoretical models for quantum feedback control now in use rely on computer simulations, which normally can only provide precise findings for certain systems.

Drawing broad, high-quality conclusions is challenging, according to Annby-Andersson.

Only a small class of feedback-controlled systems—often referred to as linear feedback—may benefit from the few models that can provide qualitative comprehension.

A "Quantum Fokker-Planck equation," created by Annby-Andersson and his associates, allows physicists to follow the development of any quantum system over time with feedback control.

According to Annby-Andersson, "the equation may explain circumstances that go beyond linear feedback." In instance, solving the equation without the use of computer simulations may be done using paper and a pen.

The group put its equation to the test by using it with a simple feedback mechanism.

This revealed how energy may be captured in tiny systems via feedback control and proved that the equation yields physically plausible outcomes.

The equation, according to Annby-Andersson, "is a good starting point for future investigations of how energy may be modified with the use of information on a microscopic level."

The team is now looking on a technique for controlling energy in "quantum dots"—tiny semiconducting crystals about billionths of a meter across—by using feedback.

The development of innovative feedback protocols that may be applied to quantum technologies using the equation as a tool is one significant future avenue, according to Annby-Andersson.
