Researchers Demonstrate Generation of Multiphoton Entangled Qubit States on Optical Chip

The optical chip developed at INRS by Prof. Roberto Morandotti’s team overcomes a number of obstacles in the development of quantum computers, which are expected to revolutionize information processing. The international research team has demonstrated that on-chip quantum frequency combs can be used to simultaneously generate multiphoton entangled quantum bit (qubit) states.

Researchers Develop New Ultra-Bright Source of Single Photons

A new ultra-bright source of single photons - 15 times brighter than commonly used sources and emitting photons that are 99.5% indistinguishable from one another - has been developed by researchers from the CNRS, Université Paris Diderot, and Université Paris-Sud.

Revolutionary Method to Flip Magnetic Bits Faster and More Energy Efficiently

Use your computer without the need to start it up: a new type of magnetic memory makes it possible. This ‘MRAM’ is faster, more efficient and robust than other kinds of data storage. However, switching bits still requires too much electrical power to make large-scale application practicable. Researchers at Eindhoven University of Technology (TU/e) have discovered a smart way of solving this problem by using a ‘bending current’. They publish their findings today in the journal Nature Communications.

Physicists Efficiently Implement Shor’s Algorithm in Ion-Trap Based Quantum Computer

Shor’s algorithm is likely the most famous quantum algorithm. He solves a centuries-old problem, namely the factoring of numbers into primes. Physicists led by Rainer Blatt joined forces with scientists at MIT, led by Isaac Chuang, to efficiently implement Shor’s algorithm in an ion-trap based quantum computer. Here their approach can be directly applied to larger numbers.

Scientists Build Quantum Computer from Five Atoms in Ion Trap

What are the prime factors, or multipliers, for the number 15? Most grade school students know the answer — 3 and 5 — by memory. A larger number, such as 91, may take some pen and paper. An even larger number, say with 232 digits, can (and has) taken scientists two years to factor, using hundreds of classical computers operating in parallel.

Scientists Demonstrate Increased Coupling of Microwaves in Specially Designed Superconducting Cavity

In what may provide a potential path to processing information in a quantum computer, researchers have switched an intrinsic property of electrons from an excited state to a relaxed state on demand using a device that served as a microwave “tuning fork.”

Researchers Investigate Light-Matter Interactions to Build Quantum Circuit Components

Quantum computers promise a vast improvement in speed over classical binary computers. The computers rely on quantum bits, or “qubits,” a system that can exist in more than one state at the same time, allowing the computers to consider multiple solutions simultaneously. Plasmons, quasiparticles arising from the collective motion of electrons on the surface of a metal, can strongly modify the behavior of nearby light, and could be instrumental in building some of the key components of a quantum circuit. But far more must be learned about their effects to develop them as a material.
