What’s our position in the universe? Some astronomers believe that the relative emptiness in our location in space may be why we haven’t found other intelligent life yet. It may even go beyond that. One theory states that our universe is actually trapped inside a giant black hole, which itself is part of a much larger cosmos.

It all centers on a very different theory of what exactly a black hole is. The usual general understanding is nothing can escape a black hole’s intense gravity, not even light. Called the black hole information paradox, it’s thought that even the information about an object that gets sucked in vanishes into oblivion. But therein lies a problem.

This understanding violates a certain rule in quantum mechanics known as “unitarity,” which states that information can never be completely lost. Some trace of it will always remain. So how can scientists get over the hump?

Three-dimensional quantum gases of strongly dipolar atoms can undergo a crossover from a dilute gas to a dense macrodroplet, stabilized by quantum fluctuations. Adding a one-dimensional…

Quantum Computers:

The Quantum computer is the next generation tech that works not with bits but with quantum bits (qubits) with optimized performance. Its working principle is based on the superposition i.e. Unlike the dualistic processing systems based on High and LOWs(0s), it can simultaneously be 1 and 0, or a mixture of both HIGH and LOW. Quantum computers are based on the laws of quantum mechanics to solve problems that are too complex for classical computers. Here are some key takeaways on how quantum computers assist DeFi to get boosted.

When quantum computers become powerful enough, they could theoretically crack the encryption algorithms that keep us safe. The race is on to find new ones.

Quantum simulators made from solid-state systems.

A phenomenon that often accompanies technological innovations involves how they tend to become smaller with their improvement over time. From televisions and communication devices like telephones to computers and microchip components, many of the technologies we use every day occupy a fraction of the space in our homes and offices that their predecessors did just decades ago.

In keeping with this trend, it is no surprise that a new tech developed by scientists at Sandia National Laboratories, in cooperation with the Max Planck Institute for the Science of Light, may soon replace cumbersome technologies than once required an entire room to operate, thanks to an ultrathin invention that could change the future of computation, encryption, and a host of other technologies.

At the heart of the invention and its function is a peculiar phenomenon that has perplexed physicists for decades, known as quantum entanglement.

The laser that will be the most powerful in the United States is preparing to send its first pulses into an experimental target at the University of Michigan.

Called ZEUS, the Zetawatt-Equivalent Ultrashort pulse laser System, it will explore the physics of the quantum universe as well as outer space, and it is expected to contribute to new technologies in medicine, electronics and national security.

An optical tweezer array is a staple tool for trapping and controlling the positions of atoms in quantum research applications. Interfering, counterpropagating lasers can perform a similar function by creating “optical lattices.” The former tool suffers from having a potential that varies from site to site, limiting the ability of the atoms to move around. The latter tool creates uniform potentials but restricts the shape to some predefined geometry. Now Zoe Yan of Princeton University and her colleagues show that they can create arbitrarily shaped, reconfigurable 2D atom lattices with uniform potentials [1]. Such traps are desirable for simulating quantum spin interactions in electronic models and exploring the behaviors of atoms in systems with complex topologies.

Yan and her colleagues create their atom arrays by sequentially adding lines of atoms until the lattice is complete. They load up to 50 cold lithium atoms into an optical tweezer. They then generate the first line of their array using a vibrating transducer, which can break up and deflect a single laser beam such that it turns into a line of light spots. Subsequent lines of the array are made with another transducer, programmed to flash on and off like a strobe light, with each line illuminated for a fraction of the strobe cycle. The result is a time-averaged 2D trap potential, where each site is independently controlled, overcoming the nonuniformity problem that previous experiments with optical tweezer arrays experienced.

Using their technique, the team has created rectangular, triangular, and octagonal-ring-shaped arrays of atoms, which they say could be used to explore the behaviors of exotic states of matter, such as chiral spin liquids.
