Quantum computers have the potential to outperform classical computers on several complex tasks, yet many challenges will need to be overcome before they reach their full potential. In the meantime, physicists and computer scientists have been trying to realistically estimate the capabilities that quantum computing technologies will exhibit in the near future.
Quantum simulations—realizations of quantum systems manifested using programmable simulation devices—have proved particularly valuable for determining the near-term potential of quantum computers. One approach that can be investigated using quantum simulations is quantum annealing, an optimization process based on engineered quantum fluctuations.
The quantum simulation of the 1D Ising chain has been done before by other research teams, including a group at Harvard University. However, the simulation carried out by King and his colleagues is the first to be conducted using an annealing-based quantum computer. In addition, the researchers were able to realize larger and more strongly correlated states than those demonstrated in the past.
Overall, the team found that their simulations were aligned with predictions of quantum theory. In the future, their work could open new and exciting possibilities for the study of different quantum phase transitions. In their next works, King and his colleagues would like to use programmable D-Wave processors to simulate more exotic quantum phase transitions, which cannot be simulated using classical computers.

I wanted to build my own quantum computer but couldn’t find a reliable parts source.
“The coherent simulation of a quantum phase transition in a programmable 2,000 qubit Ising chain...”
I was just discussing this with an 21 y/o girl in yoga pants and a sports bra at the gym today..
Hell yeah! Science!!
This is why I’ll never get a Nobel Prize in Physics. I’ve been working in my basement for 12 years now.
And the best I can do is a programmable 400 qubit Ising chain.
lol, perfect
We’re in love now...
I’ve watched the explanation of the “Dual Slit Experiment” like 100 times. I understand the words they are saying, but I still don’t understand how it’s possible.
I would need a freshly oiled Jackhammer to break into that quoted statement.
Quantum annealing is used mainly for problems where the search space is discrete with many local minima; such as finding the ground state of a spin glass or the traveling salesman problem."
Question: Is this last problem X-rated?
“ This is why I’ll never get a Nobel Prize in Physics. I’ve been working in my basement for 12 years now. And the best I can do is a programmable 400 qubit Ising chain.”
I solved that problem, but I’m still at only a 1300 qubit Ising chain. I’m missing something. I think I need more cowbell.
“Spooky action at a distance” - Albert Einstein
I was kidding around in my post #6, but I taught college physics for a few years. One thing about modern physics. You’ve kinda have to suspend common sense, and go where the evidence takes you.
Consider, for example, a moving object, any moving object. The faster it goes, the more mass (weight) it gains. Einstein worked the math out back in 1905. But it just doesn’t make sense. And it’s not noticeable for the slow-moving objects were familiar with.
But experiments have since proven that Einstein was right. Fast-moving electrons have more mass than slower ones. And by just the amount that Einstein predicted.
When you can’t understand even the headline you should show up and admit it.
I’m here to turn myself in.
I think the quantum chain is a quisling and the common sense needed to wipe bit chains/coin better than Hillary, would have to be something the FBI seriously takes up, especially when they are investigating Schrödinger for the equation that produces a dead cat in every cardboard box this side of Texas. Think about it! What terrorist wouldn’t love a quantum machine that can show you the community of electrons that you control with your mind. The subatomic is just the inverse of the normal atomic where we are fiddling with forces that could bite our asses.

It is a fascinating and weird experiment, which shows are current models don’t yet provide a good explanation of what is going on in the physical world.
Check wit dat chinks.
Matter changes by observation, it makes my brain hurt.
