MIT engineers have developed a new type of artificial synapse that’s extremely energy efficient and ultra-fast, processing data a million times faster than synapses in the human brain. The analog device shuttles protons around instead of electrons.
-
Engineers at MIT have developed a modular computer chip with components that can communicate using flashes of light. This could allow for electronics that can easily be upgraded with new sensors or processors, rather than replacing the whole chip.
-
A quantum processor, developed by German-Australian start-up Quantum Brilliance, runs at room temperature, and will now work in tandem with classical supercomputers at the Pawsey Supercomputing Research Centre.
-
Scientists in the Netherlands have made a major step towards quantum computer networks by teleporting quantum information between two nodes without a direct link to each other. The breakthrough heralds a faster and more secure communication system.
-
Heat is a major hurdle for electronic devices. Scientists have now found that nanowires made of a certain isotope of silicon can conduct heat 150 percent better than regular silicon, potentially leading to drastically cooler computer chips.
-
Researchers have now developed the fastest logic gates ever created, by zapping graphene and gold with laser pulses. The new logic gates are a million times faster than those in existing computers, demonstrating the viability of “lightwave electronics.”
-
A TU Delft team has demonstrated a one-way superconductor that gives zero resistance in one direction, but blocks current completely in the other. The discovery, long thought impossible, heralds a 400x leap in computing speed and huge energy savings.
-
Researchers in Japan have developed a new method for making 2-in wafers of diamond that could be used for quantum memory. The ultra-high purity of the diamond allows it to store a staggering amount of data – the equivalent of a billion Blu-Ray discs.
-
Apple has unveiled new desktop computers and monitors at its keynote presentation today. The Mac Studio is a new desktop workstation running on a powerful new processor, and the Studio Display is a new ultra-HD Retina screen.
-
Researchers have demonstrated key tech that could help scale up quantum computers, creating a model with a record-breaking 512 qubits. The team combined atoms of two elements into an array, so atoms can be manipulated without disturbing their neighbors.
-
Random numbers are crucial for computing, but our current algorithms aren’t truly random. Researchers at Brown University have now found a way to tap into the fluctuations of skyrmions to generate millions of truly random numbers per second.
-
Quantum computers are so far held back by their complexity. Engineers at Stanford have now demonstrated a new relatively simple design for a quantum computer where a single atom is entangled with a series of photons to process and store information.
