Honeywell releases details of its ion trap quantum computer

About a year ago, Honeywell announced that it had entered the quantum computing race with a technology that was different from anything else on the market. The company claimed that because the performance of its qubits was so superior to those of its competitors, its computer could do better on a key quantum computing benchmark than quantum computers with far more qubits.

Now, roughly a year later, the company finally released a paper describing the feat in detail. But in the meantime, the competitive landscape has shifted considerably.

Researchers realize resonant tunnelling diodes based on twisted black phosphorus homostructures

In recent years, electronics engineers worldwide have been trying to develop new semiconductor heterostructure devices using atomically thin materials. Among the many devices that can be fabricated using these materials are resonant tunneling diodes, which typically consist of a quantum-well structure placed between two barrier layers.

Past research has shown that stacking two-dimensional (2D) layers that are twisted in relation to each other can enhance or suppress the interlayer coupling at their interface. This suppression or enhancement can in turn modulate the electronic, optical and mechanical properties of the resulting .

For instance, some studies found that the intralayer current transport in small angle twisted bilayer graphene prompted some exotic phenomena, such as superconductivity and ferromagnetism. These observations inspired a fundamentally new approach to device engineering, known as ‘twistronics’ (i.e., twist electronics).

Microsoft adopts boiling liquid to cool datacenter servers

Microsoft has implemented boiling liquid to help keep datacenter servers at reasonable temperatures. The company uses electronic equipment and liquid capable of boiling at 122 degrees Farenheit, 90 degrees below the boiling point of water.

Once the processors within the datacenters reach a certain temperature due to labor, the boiling effect moves heat away from the servers. This movement allows the processors to continue operating at full power without the risk of failure from overheating.

Microsoft engineered this solution using a tank that takes the fluid vapor from its liquid contents and exposes the mist to a cooling lid. This process transforms that vapor back into liquid and rain down onto the servers in order to cool the machines. This process of vaporization and condensation for cooling is known as a closed loop cooling system.

Display Driver Chip Shortage Leads to Delays for Pretty Much Everything

Bottom dollar.

Bloomberg today reported that a shortage of inexpensive display driver chips has delayed production of the LCD panels used in, well, pretty much every product category you can think of. Displays are ubiquitous, and many devices can’t function without them. But for the displays to work, they require a display driver — no, not Nvidia or AMD display drivers, those are software. We’re talking about a tiny chip that sends instructions and signals to the display.

That’s a fairly simple function, at least compared to those performed by the vastly more powerful components inside the device proper, which is why many display drivers cost $1. But a component’s price doesn’t always reflect its importance, as anyone who’s built a high-end PC, bought one of the best gaming monitors, and then realized they forgot to get a compatible cable can attest. That missing link is both cheap and vital.

Tiny brains grown in 3D-printed bioreactor

Scientists from MIT and the Indian Institute of Technology Madras have grown small amounts of self-organizing brain tissue, known as organoids, in a tiny 3D-printed system that allows observation while they grow and develop. The work is reported in Biomicrofluidics.

Current technology for real-time observation of growing organoids involves the use of commercial culture dishes with many wells in a glass-bottomed plate placed under a microscope. The plates are costly and only compatible with specific microscopes. They do not allow for the flow or replenishment of a nutrient medium to the growing tissue.

Recent advances have used a technique known as microfluidics, where a nutrient medium is delivered through small tubes connected to a tiny platform or chip. These are, however, expensive and challenging to manufacture.

It better come with a decent meal and reclining seats for that price. It’s a one-way trip too, so you better LOVE Mars.
