By shooting a laser pulse imitating the Fibonacci Sequence into qubits, physicists created a new phase of matter far better at maintaing a quantum state.

Basically the fibonacci sequence stabilized the quantum computers internal processes better essentially. This may fall into the theory of everything that supersymmetry and the fibonacci sequence can get us closer to a theory of everything even in quantum computers.
A dynamical topological phase with edge qubits that are dynamically protected from control errors, cross-talk and stray fields, is demonstrated in a quasiperiodically driven array of ten 171Yb+ hyperfine qubits in a model trapped-ion quantum processor.
Quantum simulators should be able to give insight on exotic physics models such as supersymmetric extensions of Standard Model. Here, the authors demonstrate a first step in this direction, realising a prototypical SUSY model (and spontaneous SUSY breaking within it) using a trapped ion quantum simulator.
A new playful demonstration of quantum pseudotelepathy could lead to advances in communication and computation.
IBM has begun installing an on-premise quantum computer at a health provider’s data center in Ohio.
Cleveland Clinic and IBM said this month that deployment work of the first private sector onsite, IBM-managed quantum computer in the United States.
O.o!!! It doesn’t need seconds counted it just knows the time on the quantum level o.o!!!!!
A quantum stopwatch made of lasers and helium atoms can measure the time that has passed with complete accuracy, without counting seconds like other clocks.
The engineering of so-called Floquet states leads to almost-perfect atom-optics elements for matter-wave interferometers—which could boost these devices’ ability to probe new physics.
Since Michelson and Morley’s famous experiment to detect the “luminiferous aether,” optical interferometry has offered valuable tools for studying fundamental physics. Nowadays, cutting-edge applications of the technique include its use as a high-precision ruler for detecting gravitational waves (see Focus: The Moon as a Gravitational-Wave Detector) and as a platform for quantum computing (see Viewpoint: Quantum Leap for Quantum Primacy). But as methods for cooling and controlling atoms have advanced, a new kind of interferometer has become available, in which light waves are replaced by matter waves [1]. Such devices can measure inertial forces with a sensitivity even greater than that of optical interferometers [2] and could reveal new physics beyond the standard model.
A multiwavelength laser source known as a frequency comb provides a new technique for atom interferometry, potentially leading to new tests of fundamental physics.
In atom interferometry, researchers use the interference of quantum waves of matter, often for high-precision experiments testing fundamental physics principles. A research team has now demonstrated a new way to produce matter-wave interference by using a frequency-comb laser—a comb-like set of spectral lines at regularly spaced frequencies [1]. The comb allowed the team to generate interference in a cloud of cold atoms. The method might ultimately be used to investigate differences between matter and antimatter.
According to the weak equivalence principle, gravity must cause both matter and antimatter to fall at the same rate (see the graphical explanation, The Equivalence Principle under a MICROSCOPE). Deviations from this principle could point to explanations for the hitherto mysterious imbalance in the amounts of matter and antimatter in the Universe. Atom interferometry could provide a test of weak equivalence through precise measurements of the free fall of antihydrogen. So far, light-based control of atom interferometry has used continuous-wave (cw) lasers [2], which can’t easily be extended to the short wavelengths in the extreme ultraviolet (XUV) that are needed for such studies of antihydrogen.
Just in time for Halloween’s spooky season, a quantum sensor now has double the spookiness by combining entanglement between atoms and delocalization of atoms.
Future quantum sensors will be able to provide more precise navigation, explore for needed natural resources, more precisely determine fundamental constants, look more precisely for dark matter, or maybe someday discover gravitational waves thanks to a team of researchers led by Fellow James K. Thompson from the Joint Institute for Laboratory Astrophysics (JILA) and the National Institute of Standards and Technology (NIST).
Thompson and his team have for the first time successfully combined two of the “spookiest” features of quantum mechanics: entanglement between atoms and delocalization of atoms. By doubling down on these “spooky” features, better quantum sensors can be made.

What are these ‘spooky’ features?
Using artificial intellgence to find possibilities while humans gauge their significance is proving to be a powerful new form of scientific discovery.
