A machine learning algorithm implemented on a quantum annealer—a D-Wave machine with 1,098 superconducting qubits—is used to identify Higgs-boson decays from background standard-model processes.

Quantum Physicists “Hold” Individual Atoms in Place for First Time
Molecule Rules
The team even managed to observe two of three atoms collide to form a molecule — a process that has never been observed on this scale before. They were surprised at how long it took compared to previous experiments and calculations.
“By working at this molecular level, we now know more about how atoms collide and react with one another,” lead author and postdoc researcher Marvin Weyland said in a statement. “With development, this technique could provide a way to build and control single molecules of particular chemicals.”
Scientists Create a 5-atom Quantum Computer That Could Make Today’s Encryption Obsolete
Circa 2016
MIT scientists have developed a 5-atom quantum computer, one that is able to render traditional encryption obsolete.
God and your cosmic consciousness in the quantum cloud
In my previous post “Cryonics for uploaders: WTF is consciousness?” I didn’t elaborate on the spiritual implications of emerging theories of consciousness and reality. Here’s a unified theory of consciousness, physics, Deity, reincarnation, afterlife, eschatology, and theo/technological resurrection wink
Mind Uploading: Cybernetic Immortality
By definition, posthumanism (I choose to call it ‘cyberhumanism’) is to replace transhumanism at the center stage circa 2035. By then, mind uploading could become a reality with gradual neuronal replacement, rapid advancements in Strong AI, massively parallel computing, and nanotechnology allowing us to directly connect our brains to the Cloud-based infrastructure of the Global Brain. Via interaction with our AI assistants, the GB will know us better than we know ourselves in all respects, so mind-transfer, or rather “mind migration,” for billions of enhanced humans would be seamless, sometime by mid-century.
I hear this mantra over and over again — we don’t know what consciousness is. Clearly, there’s no consensus here but in the context of topic discussed, I would summarize my views, as follows: Consciousness is non-local, quantum computational by nature. There’s only one Universal Consciousness. We individualize our conscious awareness through the filter of our nervous system, our “local” mind, our very inner subjectivity, but consciousness itself, the self in a big sense, our “core” self is universal, and knowing it through experience has been called enlightenment, illumination, awakening, or transcendence, through the ages.
Any container with a sufficiently integrated network of information patterns, with a certain optimal complexity, especially complex dynamical systems with biological or artificial brains (say, the coming AGIs) could be filled with consciousness at large in order to host an individual “reality cell,” “unit,” or a “node” of consciousness. This kind of individuated unit of consciousness is always endowed with free will within the constraints of the applicable set of rules (“physical laws”), influenced by the larger consciousness system dynamics. Isn’t too naïve to presume that Universal Consciousness would instantiate phenomenality only in the form of “bio”-logical avatars?
Correcting the jitters in quantum devices
Labs around the world are racing to develop new computing and sensing devices that operate on the principles of quantum mechanics and could offer dramatic advantages over their classical counterparts. But these technologies still face several challenges, and one of the most significant is how to deal with “noise”—random fluctuations that can eradicate the data stored in such devices.
A new approach developed by researchers at MIT could provide a significant step forward in quantum error correction. The method involves fine-tuning the system to address the kinds of noise that are the most likely, rather than casting a broad net to try to catch all possible sources of disturbance.
The analysis is described in the journal Physical Review Letters, in a paper by MIT graduate student David Layden, postdoc Mo Chen, and professor of nuclear science and engineering Paola Cappellaro.
Quantum superposition of molecules beyond 25 kDa
Matter-wave interference experiments provide a direct confirmation of the quantum superposition principle, a hallmark of quantum theory, and thereby constrain possible modifications to quantum mechanics1. By increasing the mass of the interfering particles and the macroscopicity of the superposition2, more stringent bounds can be placed on modified quantum theories such as objective collapse models3. Here, we report interference of a molecular library of functionalized oligoporphyrins4 with masses beyond 25,000 Da and consisting of up to 2,000 atoms, by far the heaviest objects shown to exhibit matter-wave interference to date. We demonstrate quantum superposition of these massive particles by measuring interference fringes in a new 2-m-long Talbot–Lau interferometer that permits access to a wide range of particle masses with a large variety of internal states. The molecules in our study have de Broglie wavelengths down to 53 fm, five orders of magnitude smaller than the diameter of the molecules themselves. Our results show excellent agreement with quantum theory and cannot be explained classically. The interference fringes reach more than 90% of the expected visibility and the resulting macroscopicity value of 14.1 represents an order of magnitude increase over previous experiments2.
The CIA Admits Psychic Abilities Are Real, But Cannot Figure Out The Science Behind It
According to a CIA document declassified on 08/07/2000 titled “Coordinate Remote Viewing (CRV) Technology 1981–1983,” submitted to the organization August 4 of 1983, coordinate remote viewing “utilized through the methodologies that have been developed…works with remarkable precision,” but the individuals who submitted it admitted that they were “unable to explain in conventional terms why it is that the co-ordinate serves as a stimulus in the manner it does.” Nevertheless, they were convinced that David Bohm’s model of quantum mechanics provided a potentially plausible explanatory hypothesis for the mechanisms that make it possible.
David Bohm was a controversial yet brilliant luminary in physics who argued that the entirety of the cosmos is populated with quantum black holes that lead from the “explicate order” of spacetime to a realm that transcends space and time which he referred to as the “implicate order.” These black holes were termed “holospheres,” and hypothesized as the mechanism which connects the implicate order to the explicate order. From the perspective of the remote viewer, it is possible that the signal line we acquire is mediated by these holospheres, which connects us with an implicate order that is conceptually more or less identical to the Eastern concept of “Akasha” or the “Akashic records,” as articulated in the work of writers such as Swami Vivekananda.
