Quantum computers must be cooled to extremely low temperatures to minimize vibrations and prevent errors.
So far, chip-based systems have been limited to inefficient and slow cooling methods.
Now, a team of researchers at MIT and MIT Lincoln Laboratory has implemented a much faster and more energy-efficient method for cooling photonic chip-based quantum computers.
Their approach achieved cooling to about 10 times below the limit of standard laser cooling.
Key to this te…

Efficient cooling method could enable chip-based trapped-ion quantum computers
Researchers demonstrated a new method of cooling trapped ions using chip-based systems, which could enable more stable and scalable quantum computers and quantum sensors.

Tangent, why does Apple not make computers like this anymore?

The US goods trade deficit hit a record $1.2T in 2025, driven by a 60% rise in imports of computers and chips to $450B since President Trump's inauguration (Ana Swanson/New York Times)

The Cost of the A.I. Boom: A Trade Deficit the President Detests
A recent surge of A.I.-related imports has become an impediment to the smaller trade deficit President Trump wants.

The Cost of Address Translation
Modern computers are not random access machines (RAMs). They have a memory hierarchy, multiple cores, and virtual memory. In this paper, we address the computational cost of address translation in virtual memory. Starting point for our work is the observation that the analysis of some simple algorithms (random scan of an array, binary search, heapsort) in either the RAM model or the EM model (external memory model) does not correctly predict growth rates of actual running times. We propose the …

It's been a rough week because so many computer things I wanted to do just were too difficult, didn't work, or I ended up spending (wasting?) too much time on them.
Some things did work though, and I learned a lot. Some of what I learned is that computers and certain companies (and people) suck, but there's always a way around things that don't work.

One of the best innovations in personal computers has been the rise of scalable UI. Everyone now expects to be able to zoom something to make it larger, or for higher density displays to work correctly and be clearer. That was unthinkable 15 years ago. We have Apple's push to Retina to thank for that.
