Teaching quantum physics to a computer

Teaching quantum physics to a computer
An international collaboration led by ETH physicists has used machine learning to teach a computer how to predict the outcomes of quantum experiments. The results could prove to be essential for testing future quantum computers. Physics students spend many years learning to master the often counterintuitive laws and effects of quantum mechanics.

AI helps reconstruct mysteries of quantum systems

AI helps reconstruct mysteries of quantum systems
The same techniques used to train self-driving cars and chess-playing computers are now helping physicists explore the complexities of the quantum world. For the first time, physicists have demonstrated that machine learning can reconstruct a quantum system based on relatively few experimental measurements. This method will allow scientists to thoroughly probe systems of particles exponentially faster than conventional, brute-force techniques.

Quantum memory stores information for hours

Quantum memory stores information for hours
Storing information in a quantum memory system is a difficult challenge, as the data is usually quickly lost. At TU Wien, ultra-long storage times have now been achieved using tiny diamonds. With quantum particles, information can be stored and manipulated – this is the basis of many very promising technologies, such as extremely sensitive quantum sensors, quantum communication or even quantum computers.

Superconductor may develop the quantum computers of the future

Superconductor may develop the quantum computers of the future
​With their insensitivity to decoherence what are known as Majorana particles could become stable building blocks of a quantum computer. The problem is that they only occur under very special circumstances. Now researchers at Chalmers University of Technology have succeeded in manufacturing a component that is able to host the sought-after particles. ​Researchers throughout the world are struggling to build a quantum computer.

Silicon qubits and light integrate quantum computing

Silicon qubits and light integrate quantum computing
A silicon-based quantum computing device could be closer than ever due to a new experimental device that demonstrates the potential to use light as a messenger to connect quantum bits of information — known as qubits — that are not immediately adjacent to each other. The feat is a step toward making quantum computing devices from silicon, the same material used in today’s smartphones and computers.

Crystal clears the path for quantum light

Crystal clears the path for quantum light
Optical highways for light are at the heart of modern communications. But when it comes to guiding individual blips of light called photons, reliable transit is far less common. Now, a collaboration of researchers from the Joint Quantum Institute (JQI), led by JQI Fellows Mohammad Hafezi and Edo Waks, has created a photonic chip that both generates single photons, and steers them around. The device, described in Science, features a way for the quantum light to seamlessly move, unaffected by certain obstacles.

Race to accelerate development of silicon quantum chip

Race to accelerate development of silicon quantum chip
The worldwide race to create more, better and reliable quantum processors is progressing fast, as a team of TU Delft scientists led by Professor Vandersypen has realised yet again. In a neck-and-neck race with their competitors, they showed that quantum information of an electron spin can be transported to a photon, in a silicon quantum chip. This is important in order to connect quantum bits across the chip and allowing to scale up to large numbers of qubits. Their work was published in the journal Science.

Quantum physics turned into possible reality

Quantum physics turned into possible reality
ETH physicists have developed a silicon wafer that behaves like a topological insulator when stimulated using ultrasound. They have thereby succeeded in turning an abstract theoretical concept into a macroscopic product. The usual procedure goes like this: you have a complex physical system and attempt to explain its behaviour through as simple a model as possible.

Quantum dot provides fast light emission and optimised brightness

Quantum dot provides fast light emission and optimised brightness
An international team of researchers from ETH Zurich, IBM Research Zurich, Empa and four American research institutions have found the explanation for why a class of nanocrystals that has been intensively studied in recent years shines in such incredibly bright colours. The nanocrystals contain caesium lead halide compounds that are arranged in a perovskite lattice structure.

Hybrid quantum network connects different qubits

Hybrid quantum network connects different qubits
Quantum information has been transferred between a cold atomic gas and a solid crystal using photons. The work was done by Nicolas Maring and colleagues at the Institute of Photonic Sciences and the Barcelona Institute of Science and Technology and could lead to significant advances in quantum computing and even the creation of a 'quantum internet'. An important challenge in building a quantum computer is how to transfer quantum bits (qubits) of information between the 'quantum nodes' of a system.
