The Entropy of Quantum Entanglement

Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lami from the University of Amsterdam have shown, through probabilistic calculations, that there is indeed, as had been hypothesized, a rule of entropy for the phenomenon of quantum entanglement.


This finding could help drive a better understanding of quantum entanglement, which is a key resource that underlies much of the power of future quantum computers. Little is currently understood about the optimal ways to make effective use of it, despite it being the focus of research in quantum information science for decades.


The second law of thermodynamics, which says that a system can never move to a state with lower entropy, or order, is one of the most fundamental laws of nature, and lies at the very heart of physics. It is what creates the "arrow of time," and tells us the remarkable fact that the dynamics of general physical systems, even extremely complex ones such as gases or black holes, are encapsulated by a single function, its entropy.     READ MORE...

Just ahead of its blowout first-quarter earnings report on April 25, Google laid off at least 200 employees from its “Core” teams, in a reorganization that will include moving some roles to India and Mexico, CNBC has learned.

The Core unit is responsible for building the technical foundation behind the company’s flagship products and for protecting users’ online safety, according to Google’s website. Core teams include key technical units from information technology, its Python developer team, technical infrastructure, security foundation, app platforms, core developers, and various engineering roles.


At least 50 of the positions eliminated were in engineering at the company’s offices in Sunnyvale, California, filings show. Many Core teams will hire corresponding roles in Mexico and India, according to internal documents viewed by CNBC.    READ MORE...

Retirement Goals

If you are 18 and plan to retire at 67 then you have 49 years to plan for your retirement...  and by the time you get to 67 the retirement age will be moved out to 70 or maybe even 75.

After high school, you have several directions you can take:

1. College
2. Community College, then college
3. Military
4. Trade School
5. Just start working somewhere

Each one of those directions has consequences but since you have a good fifty years to work, you could look at that time as TWO TWENTY-FIVE YEAR CAREERS...   that way, if you don't like one direction, you can move into another direction.

Each of these directions is going to require different amounts of money - some may require no money at all, like the military.

BUT REGARDLESS OF THE DIRECTION, at the end of your career is RETIREMENT and your retirement income will no doubt be substantially less than your working income.

What kinds of things should you be thinking about?

• Will you get married?
• How many children?
• Will you pay for their education?
• How many homes will you own?
• How many cars will you own?
• How much debt are you willing to live with?
• At what age would you like to be debt free?
• Are you willing to relocate to different cities?
• Are you willing to relocate to different states?
• How much money would you like to save each year?
• How will you invest your extra money?
• What type of quality of life do you want?
• What is your current lifestyle?  Will it change?
• How healthy do you want to be?
• Do you smoke cigarettes?
• Do you use recreational drugs?
• How much alcohol do you drink?
• Are you willing to bag your lunch?
• Do you have to purchase a new car?
• What level of income do you need for retirement?

The answers to many of the questions, if not all of these questions will change as you get older.  Therefore, if you are thoughtful enough to answer these questions at age 18 or 20, hold onto your work because it will change at ages: 30-40-50-60 and you will not have to start from scratch.

What I am suggesting is a retirement plan - one that is fluid and changes as you change, as you needs change.  A plan is not something that you have to follow perfectly - it is a suggestion, a guide, perhaps even a goal to reach.  Just don't push that goal out so far it is impossible to reach.

BUT FIRST,

You must know yourself.  Who are you and what do you want?  In what do you believe?  Is there something that you would like to be the best at?  If so, are you willing to sacrifice doing other things in order to reach that goal?

You will need to know yourself before you can develop a plan but once you do, your plan will be a natural extension of who you are?  Or, who you want to be?

Quantum Challenge Solved Underground

Radiation from space is a challenge for quantum computers as their computation time becomes limited by cosmic rays. Researchers from Chalmers University of Technology, Sweden, and University of Waterloo in Canada are now going deep underground in the search for a solution to this problem—in a two-kilometer-deep mine.

A recently discovered cause of errors in quantum computers is cosmic radiation. Highly charged particles from space disturb the sensitive qubits and cause them to lose their quantum state, as well as the ability to continue a calculation. 

But now quantum researchers from Sweden and Canada will join forces to find a solution to the problem—in the world's deepest located clean room, two kilometers underground.  READ MORE...

China's Newest Aircraft Carrier

Seoul, South Korea (CNN) — China’s newest, largest and most-advanced aircraft carrier, the Fujian, took a big step to joining the world’s largest naval fleet on Wednesday as it set out from Shanghai for its first sea trials.

The naval assessment is expected to take place in the East China Sea, about 130 kilometers (80 miles) from the Jiangnan Shipyard where the carrier has been under construction for more than six years, according to Shanghai’s Maritime Safety Administration.

“The sea trials will primarily test the reliability and stability of the aircraft carrier’s propulsion and electrical systems,” read an announcement from the state-run Xinhua news agency on Wednesday.

The warship was launched in 2022 and has “completed its mooring trials, outfitting work and equipment adjustments” working up to the latest sea trials, Xinhua said.

With a displacement of 80,000 metric tons, the Fujian dwarfs the People’s Liberation Army Navy’s (PLAN) two active carriers, the 66,000-ton Shandong and the 60,000-ton Liaoning. Only the United States Navy operates bigger aircraft carriers than Fujian.   READ MORE...
