Trapped-ion quantum computers are quantum devices in which trapped ions vibrate together and are fully isolated from the external environment. These computers can be particularly useful for investigating and realizing various quantum physics states.
Researchers at NIST/University of Maryland and Duke University have recently used a trapped-ion quantum computer to realize two measurement-induced quantum phases, namely the pure phase and mixed or coding phase during a purification phase transition. Their findings, published in a paper in Nature Physics, contribute to the experimental understanding of many-body quantum systems.
To measure the purification phase transition first outlined by Gullans and Huse, the researchers had to average data collected over several random circuits. In addition, the measurements they collected included both unitary and projective measurements.
According to theoretical predictions, the purification phase transition probed by the team should have emerged at a critical point, resembling a fault-tolerant threshold. Noel and her colleagues carried out their experiments on random circuits that were optimized to work well with their ion-trap quantum computer. This allowed them to observe the different phases of purification using a relatively small system.
Using their trapped-ion quantum computer, the team was able to probe both the pure phase of the purification phase transition and the mixed or coding phase. In the first of these states, the system is rapidly projected to a pure state, which is related to the measurement outcomes. In the second, the system's initial state is partly encoded into a quantum error correcting coding space, which retains the system's memory of its original conditions for a longer time.

I did this in my garage several years ago - but would anyone
listen to me, or believe me? Noooooo....

“the measurements they collected included both unitary and projective measurements. “
Therein lies the problem...
“... the purification phase transition probed by the team should have emerged at a critical point, resembling a fault-tolerant threshold...”
I was just discussing this with the grocery check out clerk today...
Grifters resorting to mad libs for funding now.
Topics like this make me feel like democrats have to feel all the time.
But to neasure they must observe and observation changes the results...
Arthur Dietrich would know all about it somehow.
Dual Slit Experiment...
Sounds better than Lotus Notes.
Lol!
All I know is that if you tape up all the air holes on the box into which Schrödinger put his annoying cat (it was spraying all over the furniture), then you don’t need to look in the box.
Let a trained actor like William Shatner read that headline.
His pausing pivots and tonal ellipses will add completely new meanings.
Hi.
Is this a Schrodinger’s cat kinda thing?

Yeh, gets back to that old H bar thing ...
👍 Yup...
Oh, what I wouldn’t do to get my hands on a trapped-ion quantum computer
