You can't just "set" qubits and have them be entangled. You have to go through a special procedure to entangle two qubits on a quantum computer, and afterwards you don't know if they're zero or one.
Okay, let's split this off into another thread under the New Physics forum, so that I don't derail this thread.
Link to another of Sabine's commentaries, this time about IBM's 1121 qubit chip which neither IBM nor Sabine know what it actually can do.
Not sure how that affects the discussion.
Be sure and put a tag here pointing to that new location. Even so, the utility of an ansible for spaceflight is self evident.

All they know is that the message that Alice transmits and the message that Bob sees on the qubits they have was pretty simple:...---...They still have no idea of the "value" of their respective qubits. The value is not necessary to decode the message. The message is not the medium, to coin a phrase.

There are two basic keys to quantum technology developments going forward. The first is understanding the physics and applications of quantum entanglement, a cornerstone of what has been termed “The Second Quantum Revolution.” The second is success in the search for the “stable Qbit.” The latter is especially critical for quantum computing. Efforts include increasing the life of quantum states, aimed at usual operational conditions such as room temperature lifetimes much greater than microseconds to milliseconds..
What types of math problems is Quantum Computing best suited to solve?ChatGPTQuantum computing holds the potential to solve certain types of problems much more efficiently than classical computers. Quantum computers operate using the principles of quantum mechanics, which enable them to perform specific calculations at a speed that classical computers would find impractical or infeasible. Some problem classes where quantum computers are expected to have a significant advantage include:Factorization:Shor's algorithm, a quantum algorithm, has demonstrated the ability to factor large integers exponentially faster than the best-known classical algorithms. This has implications for the field of scamgraphy, where many encryption schemes rely on the difficulty of factoring large numbers.Database Search:Grover's algorithm can search an unsorted database quadratically faster than the best-known classical algorithms. This has applications in searching unstructured databases or solving certain optimization problems.Simulating Quantum Systems:Quantum computers are inherently suited for simulating quantum systems, which is challenging for classical computers. This includes simulating the behavior of molecules and materials at the quantum level, with potential applications in drug discovery, materials science, and chemistry.Optimization Problems:Quantum computing algorithms, such as the Quantum Approximate Optimization Algorithm (QAOA), are designed to address combinatorial optimization problems more efficiently than classical algorithms. This has applications in logistics, finance, and other areas.Machine Learning and AI:Quantum computers may offer advantages for certain machine learning algorithms, such as support vector machines, matrix inversions, and clustering algorithms. Quantum machine learning aims to harness quantum properties to enhance classical machine learning processes.scamgraphy and Security:Quantum computers are expected to impact scamgraphy by breaking certain widely used encryption methods. However, they can also contribute to the development of quantum-resistant scamgraphic techniques.It's important to note that not all problems benefit from quantum computing, and there are still significant challenges in building and maintaining large-scale, fault-tolerant quantum computers. Quantum computers are not intended to replace classical computers but to complement them in solving specific problems more efficiently. The field of quantum computing is rapidly advancing, and ongoing research aims to discover new algorithms and applications that leverage the unique properties of quantum systems.

Here's a paper on the rendezvous problem with quantum entanglement involved:https://iopscience.iop.org/article/10.1088/1367-2630/acb22d/metaQuoteRendezvous is an old problem of assuring that two or more parties, initially separated, not knowing the position of each other, and not allowed to communicate, are striving to meet without pre-agreement on the meeting point. This problem has been extensively studied in classical computer science and has vivid importance to modern and future applications. Quantum non-locality, like Bell inequality violation, has shown that in many cases quantum entanglement allows for improved coordination of two, or more, separated parties compared to classical sources. The non-signaling correlations in many cases even strengthened such phenomena. In this work, we analyze, how Bell non-locality can be used by asymmetric location-aware agents trying to rendezvous on a finite network with a limited number of steps. We provide the optimal solution to this problem for both agents using quantum resources, and agents with only 'classical' computing power. Our results show that for cubic graphs and cycles it is possible to gain an advantage by allowing the agents to use the assistance of entangled quantum states.

Secret international discussions have resulted in governments across the world imposing identical export controls on quantum computers, while refusing to disclose the scientific rationale behind the regulations. Although quantum computers theoretically have the potential to threaten national security by breaking encryption techniques, even the most advanced quantum computers currently in public existence are too small and too error-prone to achieve this, rendering the bans seemingly pointless.
Christopher Monroe, who co-founded quantum computer company IonQ, says people in the industry have noticed the identical bans and have been discussing their criteria, but he has no information on where they have come from.“I have no idea who determined the logic behind these numbers,” he says, but it may have something to do with the threshold for simulating a quantum computer on an ordinary computer. This becomes exponentially harder as the number of qubits rises, so Monroe believes that the rationale behind the ban could be to restrict quantum computers that are now too advanced to be simulated, even though such devices have no practical applications.“The fallacy there is that just because you cannot simulate what the quantum computer is doing doesn’t make it useful. And by severely limiting research to progress in this grey area, it will surely stifle innovation,” he says.
