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.
-
This month marks the 50th anniversary of Intel's 4004 processor, the first commercially available microprocessor built on a single chip. Originally designed for a Japanese desk calculator, it helped spark the personal computer revolution.
-
IBM has unveiled the Eagle, the world’s most powerful quantum processor. Boasting 127 quantum bits (qubits), the Eagle is a major step towards commercial quantum computers outperforming traditional machines.
-
For now, quantum computers are mostly limited to labs and big experimental setups. But Japanese researchers have now made a step towards more accessible quantum computing devices, finding a way to “twist” light at room temperature.

Most of us can give Pi to four or five digits, but Swiss scientists have broken the world record. It took three and a half months and a data center’s worth of computer equipment, but the researchers calculated Pi to a staggering 62.8 trillion digits.
