You can start getting pumped about the next generation of graphics cards, as Samsung has announced that it’s building the first-ever 16-gigabit GDDR6 chips using its 10-nanometer class technology. The news isn’t a complete surprise, as Samsung previously said that GDDR6 was coming when it unveiled 8-gigabit DDR4 RAM chips last month and won a CES 2018 Innovation Award in November.

“Beginning with this early production of the industry’s first 16Gb GDDR6, we will offer a comprehensive graphics DRAM line-up, with the highest performance and densities, in a very timely manner,” said Samsung’s Senior VP Jinman Han. The company also did a minor tease, saying the chips “will play a critical role in early launches of next-generation graphics cards and systems.”

The voracious demand from bitcoin mining has pushed the GeForce GTX 1070 from a $380 suggested retail price to $890.

Over the past year, Google has demonstrated its desire to step up its hardware game. The company bought HTC’s Pixel team for $1.1 billion, designed its own imaging chip for the Pixel 2 and also hired a key Apple chip designer. Bloomberg reports that in its bid to gain an edge on the competition, Google has quietly snapped up UK startup Redux, a small team focused on delivering sound and touch feedback via mobile displays.

According to filings, Google took control of the startup back in August and then subsequently shut down the company’s website. Previous demonstrations show Redux playing back music via a tablet device, which possesses tiny actuators that vibrate the screen and effectively turn it into a loudspeaker. By eliminating the need for smartphone speakers, Google may be able free up more space for batteries and other important components inside future smartphones.

From afar, it looks like a steampunk chandelier. An intricate collection of tubes and wires that culminate in a small steel cylinder at the bottom. It is, in fact, one of the most sophisticated quantum computers ever built. The processor inside has 50 quantum bits, or qubits, that process tasks in a (potentially) revolutionary way. Normally, information is created and stored as a series of ones and zeroes. Qubits can represent both values at the same time (known as superposition), which means a quantum computer can theoretically test the two simultaneously. Add more qubits and this hard-to-believe computational power increases.

Last November, IBM unveiled the world’s first 50-qubit quantum computer. It lives in a laboratory, inside a giant white case, with pumps to keep it cool and some traditional computers to manage the tasks or algorithms being initiated. At CES this year, the company brought the innards — the wires and tubes required to send signals to the chip and keep the system cool — so reporters and attendees could better understand how it works. The biggest challenge, IBM Research Vice President Jeffrey Welser told me, is isolating the chip from unwanted “noise.” This includes electrical, magnetic and thermal noise — just the temperature of the room renders the whole machine useless.

Researchers at Princeton University have constructed silicon hardware that can control quantum behaviour between two electrons with extremely high precision.

The team constructed a two qubit gate that controls interactions between the electrons in a way that allows them to act as the qubits necessary for quantum computing. The demonstration of the gate is being seen as an early step in building a more complex quantum computing device from silicon.

The gate was constructed by layering aluminium wires onto a highly ordered silicon crystal. The wires deliver voltages that trap two single electrons, separated by an energy barrier, in a double quantum dot.

What are some of the things you don’t think machines are ever going to be able to do? Computers are still very weak when it comes to understanding. They can’t process a textbook and use the knowledge the way humans do. But that’s being worked on. There’s no real problem- solving limit to what can be done. Understanding what does it mean in terms of consciousness or anything like that, I know that the software won’t be in that realm at all. But it will be an incredible problem solver.


Microsoft founder Bill Gates spoke with TIME’s Nancy Gibbs about looking forward and what makes him optimistic about the future.
