n^n^n^n^n^n is an upper bound for general n, but the special case of only 2 people can be done with just 1 query. the algorithm is just to have person A cut into two equal slices and then person B choose their favorite…
Yep, this is it. The key is not that there are two time dimensions but two independent time translation symmetries, each which translates the system by a different period of time corresponding to the two frequencies in…
does anyone know if you could take a window and make it always be in the background -- the reverse of "always on top", say "always on bottom"? doesn't seem to be an option on Mac or in Gnome that I can tell but maybe…
looks great. wish I could break it free from the browser though. a browser tab can't really be the backdrop to my work, and clicking into a browser tab just to view the visualization is an extra distraction -- defeating…
My understanding is that this project is more of a way for established researchers in a very theoretical field to start thinking about climate while using their existing skill sets to contribute.
In the long term, if we eventually make it to the scenario where we stop putting CO2 into the atmosphere on net, then each kg of CO2 input into the atmosphere must be compensated by a kg of CO2 removed by some mechanism…

how do you know the passionate to the point of addiction Yang supporters are real? I think its likely that many are, but that there are also many passionate supporters of the other candidates who just lurk on Twitter…
Someone should make a Twitter-like that verifies posters at various levels based on humanness/geographic locale and other characteristics. Then posters could limit conversations to those with >90% human score (with…
There seems to be a lot of confusion here about the complexity, for example calling the simulation here "in the linear regime" due to IBMs result. This is inaccurate. A source of this confusion is that we need to…
No. I think this is where your logic is off: "Furthermore, I think that if I try to read an entangled state, it's as if I am reading the entire state all at once" You can't read the entire state. A quantum channel where…
> The climate change argument for EVs is kind of weak, since you still have to produce the electricity I also find this line of reasoning problematic. The climate change effect of EVs is _indirect_, but that doesn't…
The question should not be whether this is too costly as compared to jet fuel, but at what carbon price is it cheaper than jet fuel? Once the cost of carbon is at the long term limit, which is equal to the cost of…
I had an idea for a minimal change to improve a Reddit-like site, perhaps you will find it interesting: split the concept of "subreddit" into "tags" and "communities". Tags: much of the content of Reddit is people…
Imagine if grocery stores forced us to choose one of a few dozen grocery "insurance" memberships to buy groceries, and negotiated directly with the insurers. No prices are labeled in store, they just detect whatever you…
In a sense, wasn't the choice to not negotiate drug costs itself the result of a negotiation? I believe the way it works is that health insurers and providers threaten to fund fear-mongering attack ads against…
What other goods is the US Gov the sole buyer of, for which the sellers can't easily shift to other customers? Cop cars clearly doesn't apply, as carmakers have other customers. Doctors, hospitals, and pharmaceuticals…
Therefore the win here is that they have verified that a 50 qubit quantum computer "works" (success rate > 10^-3 > 0.) No classical computer could verify a 100 qubit quantum computer in the same way (but you could…
There's additional piece to this that you are missing: while the classical simulation is _hard_ (i.e. increasingly hard for larger and larger number of qubits or circuit depths), it _can_ be computed with enough…
They explain in the paper that the quantity plotted in Fig. 4 can also be interpreted as a probability of zero errors of running the circuit. You can see that it goes down quickly with number of qubits and number of…
I'm not an expert, but you are correct in that there is no error correction here, and error correction is still a long way off. Around 2016, realizing that running useful quantum algorithms was a long way away and there…
It may be that the use of photons gives long coherence in these devices as compared to other types of potential qubits, but then you still have to ask about (coherence time) / (gate time).
Any evidence that these are quantum coherent devices? In seems like the only reference in the paper is that "future improvements" will allow entanglement generation. I don't think the use of "closes in" in the HN title…
The quantum states only have discrete frequencies because they are bound states contained within a trap. If you consider H = p^2/2m, a free particle, the frequencies are continuous. The universe isn't a trap.
