Quantum gravity is a theory that has been the target of decades of study by physicists worldwide. If this idea is proven, it would tie together the General Theory of Relativity (which governs gravitational fields) with quantum mechanics, and the bizarro-world of subatomic particles.
Gravitational waves, produced by accelerating objects, ripple through space-time, according to most interpretations of the General Theory of Relativity penned by famed physicist Albert Einstein. Researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) have announced they detected these disturbances in the fabric of time and space for the first time.

I have mentioned in my previous posts about the Quantum Internet work that Los Alamos has been leading; today Los Alamos has been awarded a patent on their Quantum Communication (QC) Optical Fiber.
Whitewood received a Notice of Allowance for a patent application that addresses issues that arise when employing quantum communications techniques to share cryptographic material over fiber networks.

Jungsang Kim is trying to create a quantum computer by controlling the frequency of a laser to within a millionth of a percent.
According to David DiVincenzo, a prominent computer scientist at IBM, researchers must meet five criteria to create a true quantum computing device.
First, Kim needs a well-defined system that can represent different states. For example, classical computers use small electrical switches made out of semiconductors to indicate a 1 or a 0. But because an atom’s quantum spin can point in an infinite number of directions, controlling its state with a high degree of reliability is very difficult. Kim’s group has demonstrated this feat with an accuracy on par with anyone in the world.

Radiation works as a ‘tuning fork’ to control the spin of electrons.
Scientists have found a new way of moving information between quantum bits in a computer. They used a highly purified sample of silicon doped with bismuth atoms (left) before fitting a superconducting aluminium resonator to it (middle and right).

Scientists at the French Atomic Energy Commission may have found a way of obtaining information from the spin of electrons on demand by using microwaves to change their spin state.
Theoretical physicists at MIT recently reported a quantum computer design featuring an array of superconducting islands on the surface of a topological insulator. They propose basing both quantum computation and error correction on the peculiar behavior of electrons at neighboring corners of these islands and their ability to interact across islands at a distance. “The lowest energy state of this system is a very highly entangled quantum state, and it is this state that can be used to encode and manipulate qubits,” says graduate student Sagar Vijay, lead co-author of the paper on the proposed system, with senior author Liang Fu, associate professor of physics at MIT, and Timothy H. Hsieh PhD ’15. As Vijay explains it, the proposed system can encode logical qubits that can be read by shining light on them. At the simplest level of explanation, the system can characterize the state of a quantum bit as a zero or a one based on whether there is an odd or even number of electrons associated with a superconducting quantum bit, but the underlying physical interactions that allow this are highly complex.
Qubits in solid state devices for transmission across an Quantum Internet is a given in order to have great performance on a Quantum Network as well as help ensuring secured transmission of information across the net — this is a given and why Quantum is a must for supporting and securing things like AI, IoT, and other emerging technologies such as Brain Interface devices.
Without this technology; it will be very hard for industries, governments, and especially consumers to embrace and adopt full automated AI, brain interface devices, etc.
A research team from the Joint Quantum Institute have developed a way for qubits to interact with photons, which could ultimately lead to futuristic quantum networks. Theorists explained that such a solid state device could give birth to compact chip-integrated quantum circuits enabling gigahertz range bandwidths.
Qubits or quantum bits which are the quantum analogue of the classical bit allows superposition of states in between horizontally polarized and vertically polarized states. Contemporary optical networks use electronic circuits to store information and an optical fibre to carry it. However, scientists sketched a quantum network system in which highly secured qubits will be transmitted using an optical fibre. However, in order to realise this in practice will require a feasible interaction between an electron and a photon.
ABSTRACT
While General Relativity (GR) ranks undoubtedly among the best physics theories ever developed, it is also among those with the most striking implications. In particular, GR admits solutions which allow faster than light motion and consequently time travel. Here we shall consider a “pre-emptive” chronology protection mechanism that destabilises superluminal warp drives via quantum matter back-reaction and hence forbids even the conceptual possibility to use these solutions for building a time machine. This result will be considered both in standard quantum field theory in curved spacetime as well as in the case of a quantum field theory with Lorentz invariance breakdown at high energies. Some lessons and future perspectives will be finally discussed.
