New research centering around the Unruh effect has created a set of necessary conditions that theories of quantum gravity must meet.
Quantum physics has, since its development in the early years of the 20th century, become one of the most successful and well-evidenced areas of science. But, despite all of its successes and experimental triumphs, there is a shadow that hangs over it.
Despite successfully integrating electromagnetic, the weak and strong nuclear forces — three of the four fundamental forces — quantum physics is yet to find a place for gravity.
This video is the ninth in a multi-part series discussing computing and the second discussing non-classical computing. In this video, we’ll be discussing what quantum computing is, how it works and the impact it will have on the field of computing.
[0:28–6:14] Starting off we’ll discuss, what quantum computing is, more specifically — the basics of quantum mechanics and how quantum algorithms will run on quantum computers.
[6:14–9:42] Following that we’ll look at, the impact quantum computing will bring over classical computers in terms of the P vs NP problem and optimization problems and how this is correlated with AI.
[9:42–14:00] To conclude we’ll discuss, current quantum computing initiatives to reach quantum supremacy and ways you can access the power of quantum computers now!

Ira Pastor Comments:
On the last several shows we have spent time on different hierarchical levels the biologic-architecture of the life, disease and aging process. We’ve spent some time talking about the genome, the microbiome, tissue engineering, systems biology, and dabbled a bit in the areas of quantum biology, organism hydro-dynamics, and even chronobiology. As exciting and promising as all these research paths are, at the end of the day, in order for them to yield what many people are looking for, that is radically extended healthspans and lifespans, there needs to be an organized system of human translation build around them, integrating these various products, services and technologies, from supplements, to biologics, to functional foods, to cosmeceuticals, to various physio-therapeutic interventions, and so forth, as well as all the related supporting advocacy and education, as biologic aging is truly a multi-factorial, combinatorial process that is never going to be amenable to big pharma’s traditional “single magic bullet” philosophy that it promoted throughout the last century.
For today’s guest, I could think of no one better to talk with us about this topic and take us into the future on this front, than Bill Faloon, Director and Co-Founder, Life Extension Foundation (LEF), a consumer advocacy organization with over 100,000 members that funds research (investing million per year in researchers around the globe) and disseminates information to consumers about optimal health, and more recently in the area of actionable clinical interventions regarding human biologic age reversal, through a fascinating new project called the Age Reversal Network, defined as an open-source communications channel to exchange scientific information, foster strategic alliances, and support biomedical endeavors aimed at reversing degenerative aging.
Bill is also the Founder of The Church Of Perpetual Life, a nonprofit transhumanist organization aiming to combine discussion integrating spirituality, community, and aging scientific research in a single unified forum.
He’s a board member of the Coalition For Radical Life Extension, which is the organizer of annual RAADfest conference (Revolution Against Aging and Death) which is the world’s largest gathering of radical life extension enthusiasts.
It’s time to celebrate another first in the field of quantum physics: scientists have been able to ‘teleport’ a qutrit, or a piece of quantum information based on three states, opening up a whole host of new possibilities for quantum computing and communication.
Up until now, quantum teleportation has only been managed with qubits, albeit over impressively long distances. A new proof-of-concept study suggests future quantum networks will be able to carry much more data and with less interference than we thought.
If you’re new to the idea of qutrits, first let’s take a step back. Simply put, the small data units we know as bits in classical computing can be in one of two states: a 0 or a 1. But in quantum computing, we have the qubit, which can be both a 0 and 1 at the same time (known as superposition).

Researchers have, for the first time, identified the sufficient and necessary conditions that the low-energy limit of quantum gravity theories must satisfy to preserve the main features of the Unruh effect.
A KAIST team has designed a novel strategy for synthesizing single-crystalline graphene quantum dots, which emit stable blue light. The research team confirmed that a display made of their synthesized graphene quantum dots successfully emitted blue light with stable electric pressure, reportedly resolving the long-standing challenges of blue light emission in manufactured displays. The study, led by Professor O Ok Park in the Department of Chemical and Biological Engineering, was featured online in Nano Letters on July 5.
Graphene has gained increased attention as a next-generation material for its heat and electrical conductivity as well as its transparency. However, single and multi-layered graphene have characteristics of a conductor so that it is difficult to apply into semiconductor. Only when downsized to the nanoscale, semiconductor’s distinct feature of bandgap will be exhibited to emit the light in the graphene. This illuminating featuring of dot is referred to as a graphene quantum dot.
Conventionally, single-crystalline graphene has been fabricated by chemical vapor deposition (CVD) on copper or nickel thin films, or by peeling graphite physically and chemically. However, graphene made via chemical vapor deposition is mainly used for large-surface transparent electrodes. Meanwhile, graphene made by chemical and physical peeling carries uneven size defects.
China has declared its ambition to dominate the technology sector from 5G and artificial intelligence to robotics and quantum computing. Joining the infrastructure firms on this year’s list are technology firms such as Alibaba, http://JD.com/, Tencent, Xiaomi, and BOE. Huawei was not included as it is a private entity.
China’s ambition to dominate the technology sector from 5G and artificial intelligence to robotics and quantum computing is bearing fruit.
When you pop a tray of water into the freezer, you get ice cubes. Now, researchers from the University of Colorado Boulder and the University of Toronto have achieved a similar transition using clouds of ultracold atoms.
In a study that will appear August 2 in the journal Science Advances, the team discovered that it could nudge these quantum materials to undergo transitions between “dynamical phases”—essentially, jumping between two states in which the atoms behave in completely different ways.
“This happens abruptly, and it resembles the phase transitions we see in systems like water becoming ice,” said study co-author Ana Maria Rey. “But unlike that tray of ice cubes in the freezer, these phases don’t exist in equilibrium. Instead, atoms are constantly shifting and evolving over time.”
