The dawning of the quantum age
The dawning of the quantum age It is a quarter of a century since the first quantum bits, or qubits, were hooked together to make a rudimentary quantum computer. With their ability to represent both the ones and zeros in traditional computers at the same time, qubits are the most basic components of systems that […]
New techniques for accurate measurements of tiny quantum objects
New techniques for accurate measurements of tiny quantum objects New research led by a team of scientists at The Australian National University (ANU) has outlined a way to achieve more accurate measurements of microscopic objects using quantum computers—a step that could prove useful in a huge range of next-generation technologies, including biomedical sensing. Examining […]
Programmable frequency-bin quantum states in a nano-engineered silicon device
Programmable frequency-bin quantum states in a nano-engineered silicon device Abstract Photonic qubits should be controllable on-chip and noise-tolerant when transmitted over optical networks for practical applications. Furthermore, qubit sources should be programmable and have high brightness to be useful for quantum algorithms and grant resilience to losses. However, widespread encoding schemes only combine at most […]
A new qubit approach for more stable states for quantum computers
A new qubit approach for more stable states for quantum computers Quantum computers can more rapidly process large amounts of data because they carry out many computation steps in parallel. The information carrier of the quantum computer is a qubit. Qubits do not only possess the information of “0” and “1,” but also values in […]
Revived photon entanglement could enhance quantum communication and imaging – Physics World
Revived photon entanglement could enhance quantum communication and imaging – Physics World Researchers in India have shown that photon entanglement in a certain continuous-variable basis revives itself as the photons propagate away from their source. The discovery could prove useful for securely transmitting quantum information over long distances and for quantum imaging in turbulent media. […]
Quantum superposition begs us to ask, “What is real?”
Quantum superposition begs us to ask, “What is real?” The world of the very, very small is a wonderland of strangeness. Molecules, atoms, and their constituent particles did not readily reveal their secrets to the scientists that wrestled with the physics of atoms in the early 20th century. Drama, frustration, anger, puzzlement, and nervous breakdowns […]
Quantum computers threaten our whole cybersecurity infrastructure: Here’s how scientists can bulletproof it
Quantum computers threaten our whole cybersecurity infrastructure: Here’s how scientists can bulletproof it Thirteen, 53, and 433. That’s the size of quantum computers in terms of quantum bits, or qubits, which has significantly grown in the last years due to important public and private investments and initiatives. It is not only a mere question of quantity: the quality of the prepared […]
Scientists See Quantum Interference between Different Kinds of Particles for First Time
Scientists See Quantum Interference between Different Kinds of Particles for First Time For the first time, scientists have observed quantum interference—a wavelike interaction between particles related to the weird quantum phenomenon of entanglement—occurring between two different kinds of particles. The discovery could help physicists understand what goes on inside an atomic nucleus. Particles act as […]
Scientists make a quantum harmonic oscillator at room temperature
Scientists make a quantum harmonic oscillator at room temperature A quantum harmonic oscillator—a structure that can control the location and energy of quantum particles that could, in the future, be used to develop new technologies including OLEDs and miniature lasers—has been made at room temperature by researchers led by the University of St Andrews.
