A world-record result in reducing errors in semiconductor ‘spin qubits’, a type of building block for quantum computers, has been achieved using the theoretical work of quantum physicists at the University of Sydney Nano Institute and School of Physics.

The experimental result by University of New South Wales engineers demonstrated error rates as low as 0.043 percent, lower than any other spin qubit. The joint research paper by the Sydney and UNSW teams was published this week in Nature Electronics and is the journal’s cover story for April.

“Reducing errors in quantum computers is needed before they can be scaled up into useful machines,” said Professor Stephen Bartlett, a corresponding author of the paper.

Electronic devices such as transistors are getting smaller and will soon hit the limits of conventional performance based on electrical currents.

Devices based on magnonic currents—quasi-particles associated with waves of magnetization, or spin waves, in certain magnetic materials—would transform the industry, though scientists need to better understand how to control them.

Engineers at the University of California, Riverside, have made an important step toward the development of practical magnonic devices by studying, for the first time, the level of noise associated with propagation of magnon current.

ETH researchers have integrated two CRISPR-Cas9-based core processors into human cells. This represents a huge step towards creating powerful biocomputers.

Controlling gene expression through gene switches based on a model borrowed from the digital world has long been one of the primary objectives of synthetic biology. The digital technique uses what are known as logic gates to process input signals, creating circuits where, for example, output signal C is produced only when input signals A and B are simultaneously present.

To date, biotechnologists had attempted to build such digital circuits with the help of protein gene switches in cells. However, these had some serious disadvantages: they were not very flexible, could accept only simple programming, and were capable of processing just one input at a time, such as a specific metabolic molecule. More complex computational processes in cells are thus possible only under certain conditions, are unreliable, and frequently fail.

At an event in Beijing, Intel debuted the Neural Compute Stick 2, which packs a Myriad X system-on-chip it claims has an 8 times performance advantage.

Next-generation, low-power optical data transmission may rely on polarization rather than switching laser pulses on and off.

Researchers hoping to better interpret data from the detection of gravitational waves generated by the collision of binary black holes are turning to the public for help.

West Virginia University assistant professor Zachariah Etienne is leading what will soon become a global volunteer computing effort. The public will be invited to lend their own computers to help the scientific community unlock the secrets contained in gravitational waves observed when black holes smash together.

LIGO’s first detection of gravitational waves from colliding black holes in 2015 opened a new window on the universe, enabling scientists to observe cosmic events spanning billions of years and to better understand the makeup of the Universe. For many scientists, the discovery also fueled expansion of efforts to more thoroughly test the theories that help explain how the universe works—with a particular focus on inferring as much information as possible about the black holes prior to their collision.
