Why would you not just have 0AD be the same year as 0BC, just like with real number where 0 = -0?

A couple of responses. The error bars on global temperature measurements are not particularly big, the analysis here [1] for the dataset I linked earlier gives 95% confidence intervals of 0.05 degrees in the annual mean for the last 50 year

Without wishing to come across as someone "going mental", it is fairly clear that the global mean temperature has been increasing https://climate.nasa.gov/vital-signs/global-temperature/ with a change of

My understanding (which is highly limited, I am a researcher in quantum information but quantum gravity is very far out of my reach) is that this essentially gives you information about degrees of freedom of "stuff" (I guess quant

Whether or not BP works as a counter example has no bearing on other examples. Aramco and ExxonMobil certainly look like a counterexamples to me.

Could you perhaps quote exactly what statement I made which is malformed? In any case the picture of time and space switching places inside a black hole is at best a rather deceptive simplification. The most important thing about the event

>Eventually individual morality will kick in and there will be a revolt against dismantling of the Earth. This does not seem to be a given. Indeed one can look at the fossil fuel industry for what looks like counterexamples.

That is indeed a fun read, but nothing in it contradicts what I said.

In addition to a hypothetical AI, it sounds like you are describing real companies here.

To match the guy I was replying to, and because the USA is primarily a political, not geographical construct so it makes sense to compare it to another political construct in the EU.

For a more accurate reference point, the EU's area is about 4.2 million km and the contiguous USA (so without Alaska etc) is about 8 million, so the EU is about half the area of the contiguous US.

Yeah this is closer to simulating a classical coin (albeit one with three sides) than a qubit.
406.
by eigenket 3y ago
In general quantum mechanics requires complex numbers, in general quantum mechanics also requires more than a single qubit as well. This is a very simplistic (maybe minimal) example.
407.
by eigenket 3y ago
That would be very surprising. They show in this work that their problem is complete for the complexity class BQP. That means that if you can solve it on a classical computer (analog or not) in polynomial time you get (for free) classical p

Thats kinda obvious I think. Either they build a quantum computer and make buckets of money, someone else builds a quantum computer and they make slightly smaller buckets of money, or no one builds a quantum computer and they fail.
409.
by eigenket 3y ago
That depends on the company, some are making money by doing research the same way universities do (by applying for grants from governments). Some are essentially selling hype (we're building this cool thing, get in on the ground floor)

I sort of agree. Quantum computing is interesting, AI is interesting, "quantum AI" is a meme and almost certainly not interesting. On the other hand the Google team do do a lot of cool research, and I assume the scientists weren&

They have exponentially many classical oscillators, but then they simulate them with their quantum algorithm with exponential speed up. The two exponential factors cancel and you end up with a quantum algorithm for a BQP complete problem wh

Its a network of exponentially many coupled classical oscillators, not quantum harmonic oscillators. This is a new result.
413.
by eigenket 3y ago
The logic gates described in that link are more complicated than just coupled harmonic oscillators. They have things like ratchets, or they block each other, or there is buckling. The quantum algorithm couldn't simulate these things.

I think the point is that there are many places where (especially indigenous) remains don't have the same level of legal protection as they do in the UK. The universities also want to make sure their researchers get permission from who

This research is being done by US and Australian universities on remains from the UK. If you turn up in the UK and try to dig up random skeletons and send them to the US or Australia without the correct permissions, you're gonna get ar

It essentially is. The right to privacy is part of the Charter of Fundamental Rights of the European Union, which is enshrined into law as part of the Treaty of Lisbon.

In a few these pictures it seems to be heavily influenced by the adaptation of I Robot with Will Smith in it for what robots look like.
