Quantum networking uses subatomic matter to deliver data in a way that goes beyond today’s fiber-optic systems. Amazon wants to grow diamonds which would be part of a component that lets the data travel farther without breaking down.
Pretty futuristic!
Amazon.com Inc. is teaming up with a unit of De Beers Group to grow artificial diamonds, betting that custom-made gems could could help revolutionize computer networks.
The human brain, with its intricate networks of neurons, has long been a subject of fascination and mystery. Concurrently, the cosmos, with its vastness and complexity, has intrigued scientists and philosophers for centuries.
Recent research has begun to explore the possibility that the brain and the cosmos might be connected on a quantum scale. This article will delve into the research paper titled “Quantum transport in fractal networks” and discuss its implications for our understanding of the relationship between the brain and the cosmos.

Many experts in the industry predict the cost of quantum computing hardware will continue to decrease over time as the technology advances, making it more accessible to a broader range of businesses and organizations. In a recent talk, the CTO of the CIA Nand Mulchandani noted that the quantum industry is still very early and unit costs are still very high, as we are very much in the research and development stage.
In general, pricing concerns are sure to be influenced by several important factors, including how advanced discoveries in the sector are made, market demand for the technology and competition among quantum computing providers.
The Quantum Insider observes with a keen eye the market trends and technological narrative that is evolving as we speak. When thinking about the price of a quantum computer price in 2023, it’s worth considering the access method, the type of computer and usage requirements.
Researchers at the Institute for Quantum Optics and Quantum Information (IQOQI) in Vienna recently devised a universal mechanism to invert the evolution of a qubit with a high probability of success. This protocol, outlined in Physical Review Letters, can propagate any target qubit back to the state it was in at a specific time in the past.
The introduction of this protocol builds on a previous paper published in 2020, where the same team presented a series of time translating protocols that could be applied in uncontrolled settings. While some of these protocols were promising, in most tested scenarios their probability of success was found to be too small. In their new study, the researchers thus set out to create an alternative protocol with a higher probability of success.
“Our newly developed protocol inverts the unitary evolution of a qubit,” David Trillo, one of the researchers who carried out the study together with Benjamin Dive and Miguel Navascués, told Phys.org. “A qubit (or quantum bit) is a two-level quantum system that serves as the quantum equivalent of bits used in quantum computers. Any quantum system has some natural evolution in time that needs to be controlled or at least accounted for when designing physical processes around them (e.g., when building a quantum computer). Our protocol takes a qubit and outputs the same system, but in the state that it would be in if it had evolved backwards in time.”
The wave-particle duality of quantum objects like photons, electrons and atoms through double-slit experiments. Now it’s time’s turn.
An international team, headed by the University of Geneva (UNIGE), has created a quantum material that allows the fabric of the space inhabited by electrons to be curved on demand.
The advent of cutting-edge information and communication technologies presents scientists and industry with new hurdles to overcome. To address these challenges, designing new quantum materials, which derive their remarkable characteristics from the principles of quantum physics, is the most promising approach.
A global collaboration headed by the University of Geneva (UNIGE) and featuring researchers from the universities of Salerno, Utrecht, and Delft, has developed a material that allows for the control of electron dynamics by curving the fabric of space in which they evolve. This advancement holds promise for future electronic devices, particularly in the field of optoelectronics. The findings were published in the journal Nature Materials.

Quantum computing promises to be a revolutionary tool, making short work of equations that classical computers would struggle to ever complete. Yet the workhorse of the quantum device, known as a qubit, is a delicate object prone to collapsing.
Keeping enough qubits in their ideal state long enough for computations has so far proved a challenge.
In a new experiment, scientists were able to keep a qubit in that state for twice as long as normal. Along the way, they demonstrated the practicality of quantum error correction (QEC), a process that keeps quantum information intact for longer by introducing room for redundancy and error removal.
An analysis and improvement of the spectral properties of nitrogen-vacancy defects in diamond nanostructures paves the way for efficient entanglement generation necessary for many quantum information applications.
