Light cage or Lattice cage is quite a problem solver! And truly is a
problem Solved!
Lattice Mazes are a solution to so many issues (I mean that, Thing Maths)

China claims quantum leap with machine declared a million times
greater than Google’s Sycamore

Physicist Pan Jianwei says his team achieved quantum supremacy but
‘further verification’ is necessary
Pan’s team has received generous and consistent support from !NGO!

Light Maze is a very interesting problem & Solution to so many hours
of boredom! :-)

Very interesting! RS

Lots of love

A Chinese physicist claimed to have built a quantum computer that
would leave Western competitors in the dust, but he and his team said
they needed to “further verify” the claim.
Pan Jianwei, a physicist from the University of Science and Technology
of China, announced at a lecture at Westlake University, Hangzhou, on
September 5 that a new machine had recently achieved “quantum
supremacy” one million times greater than the record currently held by
Sycamore, a quantum computer built by Google.
Sycamore completed in about 200 seconds a calculation that would keep
the fastest computer on Earth busy for 10,000 years, according to a
paper published by Google researchers last year.
Pan’s claim was reported by Anhui Daily and other media on the mainland.
Pan’s team issued a statement on Weibo on Tuesday that they were
“deeply worried” by these reports because Pan had been quoted out of
context.
The results were still preliminary, and there was “no 100 per cent
guarantee until further verification,” Pan was quoted as saying in the
statement.
By the time of publishing this South China Morning Post report, Pan’s
team had not released a paper to provide more details about their
work.
A quantum computer uses qubits, or subatomic particles in various
quantum states to perform many calculations at the same time. Some
scientists believe the technology could one day be used to hack into a
bank account protected by a password, among other applications.
A general purpose quantum computer could still be decades away,
however. Most existing machines perform only very specific tasks and
have nothing to do with code breaking.

Pan’s quantum computer, for instance, simulates how light bounces
through a chamber filled with crystals. When a particle of light hits
a crystal, it goes either left or right and hits another crystal, and
then another. As the number of light particles increases, the
situation becomes extremely complicated. Simulating this process could
strain the resources of the most powerful computer, but would be much
easier on a quantum computer.
When Pan’s team started building a device to perform this particular
task, known as boson sampling, it could handle 10 qubits. Now they
have achieved 50 qubits, according to Pan.

Google’s Sycamore handles 53 qubits but was built with a different
design, known as “random circuit”, to deal with a different task.
Neither Pan nor his team explained how they compared the performance
of the two machines.
Both were built to demonstrate “quantum supremacy”, or the idea that
quantum computers could do better than their conventional
counterparts, at least on some specific tasks.
But the idea was not without controversy. IBM, for instance, alleged
that Google had exaggerated their claim by using an outdated algorithm
that stretched the runtime on supercomputers from two days to over
10,000 years.
Pan led the development of the world’s first quantum satellite and the
construction of the longest quantum communication network from Beijing
to Shanghai which, in theory, could not be tapped into. His team has
received generous and consistent financial support from the Chinese
government for nearly two decades to bring China‘s quantum technology
to a world-leading position.
A scientist in his team said they were under pressure to prove the
worth of the government’s investments.
“Not all fundamental research work has an immediate application in
sight,” said the physicist who asked not to be named because of the
sensitivity of the issue.
A major challenge for quantum computing is that it usually needs to
work in extremely cold and isolated environments. Subatomic particles
are fragile, short-lived and prone to error with even slight
disturbance from the surroundings.

The Berkeley Newsletter says

The Berkeley Newsletter says that  Berkeley has received a 25 million $ grant from the National Science Foundation to develop a quantum computer. The Department of Energy has allowed a 105 million $ grant to the MIT for a similar project. Let us wait and see.
