![]() This tutorial is not a declaration that I know all things about curing bacon. Having said that, you should always be cautious when using curing salts to make sure that you measure correctly and follow safe curing and cooking methods. The 1 ounce (heaping TBS) that I use and recommend for 1 gallon of water in this recipe is bare minimum usage and only for reproduction of flavor that we have come to expect in our bacon. I leave the dry curing and cold smoking of bacon to the professionals. That argument, at least, doesn't apply to the open kind, because any messages from the future would be locked.I studied this for years before I attempted to tell anyone else how to do it and, even so, I only recommend wet curing, semi-hot smoking and cooking the meat to safe eating temperatures since that is the safest method. ![]() One argument against closed timelike curves is that no-one from the future has ever visited us. There is a caveat - not all physicists think that these open timeline curves are any more likely to be realisable in the physical universe than the closed ones. "The reason there is an effect is because some information is stored in the entangling correlations: this is what we're harnessing," Thompson says. But it does: quantum particles sent on a timeloop could gain super computational power, even though the particles never interact with anything in the past. "Whenever we present the idea, people say no way can this have an effect" says Jayne Thompson, a co-author at CQT. ![]() His eight other coauthors come from these institutions, the University of Oxford, UK, Australian National University in Canberra, the University of Queensland in St Lucia, Australia, and QKD Corp in Toronto, Canada. Gu is at the Centre for Quantum Technologies (CQT) at the National University of Singapore and Tsinghua University in Beijing. "We avoid 'classical' paradoxes, like the grandfathers paradox, but you still get all these weird results," says Mile Gu, who led the work. Nevertheless, the strange quantum properties that permit "impossible" computations are left intact. That's because they don't allow direct interaction with anything in the object's own past: the time travelling particles (or data they contain) never interact with themselves. However, the new work shows that a quantum computer can solve insoluble problems even if it is travelling along "open timelike curves", which don't create causality problems. Over the past two decades, researchers have shown that foundational principles of quantum physics break in the presence of closed timelike curves: you can beat the uncertainty principle, an inherent fuzziness of quantum properties, and the no-cloning theorem, which says quantum states can't be copied. Breaking the causal flow of time has consequences for quantum physics too. Physicists argue something must stop such opportunities arising because it would threaten 'causality' - in the classic example, someone could travel back in time and kill their grandfather, negating their own existence.Īnd it's not only family ties that are threatened. ![]() General relativity allows such paths to exist through contortions in spacetime known as wormholes. These are paths through the fabric of spacetime that loop back on themselves. The problem was, Bacon's quantum computer was travelling around 'closed timelike curves'. These correlations can fuel a quantum computation.Īround ten years ago researcher Dave Bacon, now at Google, showed that a time-travelling quantum computer could quickly solve a group of problems, known as NP-complete, which mathematicians have lumped together as being hard. Entanglement, a strange effect only possible in the realm of quantum physics, creates correlations between the time-travelling message and the laboratory system. This is true if the experimenter entangles the message with some other system in the laboratory before sending it. ![]() It turns out that an unopened message can be exceedingly useful. ![]()
