Quantum Computing With Diamonds: Researchers Create A Single-Chip Quantum 'Bridge'

International Business Times

The race to build a scalable and viable quantum computer is driven by the thirst to create an extremely fast and powerful device -- one that would make today's computers look like old, doddering abacuses by comparison. Consider this, then -- if one quantum computer can be orders of magnitude more powerful than its conventional counterpart, what can a series of interconnected quantum computers achieve? It is this question that motivated researchers at Sandia National Laboratories in Albuquerque, New Mexico, and Harvard University to demonstrate a technique for connecting, or "bridging," quantum computers at an atomic scale. "People have already built small quantum computers," Ryan Camacho, a researcher at Sandia National Laboratories, and co-author of a study detailing the process, said in a statement. "Maybe the first useful one won't be a single giant quantum computer but a connected cluster of small ones."

Quantum Computing: A glimpse The Informatica


From the start of computing history, the power of our CPU's is growing exponentially. Henceforth allowing the computer systems to be smaller and more powerful, but this joy ride is about to come to an end. To understand why, first we need to understand the greatest prediction of the 20th century which held on for more than 50 years. Yes, I am talking about the Moore Law, which is named after the Gordon Moore cofounder of Fairchild Semiconductors and CEO of the Intel. The number of transistors in a dense integrated circuit, double about every two years, though the cost of the system is halved.

Scaling Up the Quantum Chip: MIT Engineers Connect Photonics With "Artificial Atoms"


This graphic depicts a stylized rendering of the quantum photonic chip and its assembly process. The bottom half of the image shows a functioning quantum micro-chiplet (QMC), which emits single-photon pulses that are routed and manipulated on a photonic integrated circuit (PIC). The top half of the image shows how this chip is made: Diamond QMCs are fabricated separately and then transferred into the PIC. MIT engineers develop a hybrid process that connects photonics with "artificial atoms," to produce the largest quantum chip of its type. MIT researchers have developed a process to manufacture and integrate "artificial atoms," created by atomic-scale defects in microscopically thin slices of diamond, with photonic circuitry, producing the largest quantum chip of its type.

7 Core Qubit Technologies for Quantum Computing - Amit Ray


Here we discussed the advantages and limitations of seven key qubit technologies for designing efficient quantum computing systems. The seven qubit types are: Superconducting qubits, Quantum dots qubits, Trapped Ion Qubits, Photonic qubits, Defect-based qubits, Topological Qubits, and Nuclear Magnetic Resonance (NMR) . They are the seven pathways for designing effective quantum computing systems. Each one of them have their own limitations and advantages. We have also discussed the hierarchies of qubit types.

Atomic-sized 'MRI scanners' may lead to new drugs

Daily Mail - Science & tech

For scientists developing new drugs, knowing the structure of the molecules involved down to the atomic level can mean the difference between a new treatment and failure. Current imaging techniques are unable to work out the structure of some key proteins and other important biological molecules, leading to gaps in knowledge. But researchers in Australia are looking to an offshoot from quantum computing to solve the problem, essentially developing quantum MRI scanners to image individual atoms, which could lead to the development of new drugs. In a mind-bending piece of theoretical research, a team at the University of Melbourne is hoping to use quantum bits to'sense' individual atoms. More known for their role in quantum computing, quantum bits, or qubits, are the able to encode multiple states at once, compared with the traditional binary of 1's and 0's.
