Hello World.
I'm Imagination.
Today I'm going to talk about Quantum computing.
Quantum computing is the use of quantum-mechanical
phenomena such as superposition and entanglement
to perform computation.
Computers that perform quantum computations
are known as quantum computers.
: Quantum computers are believed to be able
to solve certain computational problems, such
as integer factorization (which underlies
RSA encryption), substantially faster than
classical computers.
The study of quantum computing is a subfield
of quantum information science.
Quantum computing began in the early 1980s
when physicist Paul Benioff proposed a quantum
mechanical model of the Turing machine.
Richard Feynman and Yuri Manin later suggested
that a quantum computer had the potential
to simulate things that a classical computer
could not.
In 1994, Peter Shor developed a quantum algorithm
for factoring integers that had the potential
to decrypt RSA-encrypted communications.
Despite ongoing experimental progress since
the late 1990s, most researchers believe that
"fault-tolerant quantum computing [is] still
a rather distant dream."
In recent years, investment in quantum computing
research has increased in both the public
and private sectors.
On 23 October 2019, Google AI, in partnership
with the U.S. National Aeronautics and Space
Administration (NASA), claimed to have performed
a quantum computation that is infeasible on
any classical computer.
There are several models of quantum computing,
including the quantum circuit model, quantum
Turing machine, adiabatic quantum computer,
one-way quantum computer, and various quantum
cellular automata.
The most widely used model is the quantum
circuit.
Quantum circuits are based on the quantum
bit, or "qubit", which is somewhat analogous
to the bit in classical computation.
Qubits can be in a 1 or 0 quantum state, or
they can be in a superposition of the 1 and
0 states.
However, when qubits have measured the result
of the measurement is always either a 0 or
a 1; the probabilities of these two outcomes
depend on the quantum state that the qubits
were in immediately prior to the measurement.
Computation is performed by manipulating qubits
with quantum logic gates, which are somewhat
analogous to classical logic gates.
Quantum computers could spur the development
of new breakthroughs in science, medications
to save lives, machine learning methods to
diagnose illnesses sooner, materials to make
more efficient devices and structures, financial
strategies to live well in retirement, and
algorithms to quickly direct resources such
as ambulances.
It's time — quantum computing is going from
something that's theoretical to practical.
And it's on its way to having a real impact.
A new partnership between Microsoft’s Azure
Quantum and Honeywell offers another way for
organizations across the globe to be introduced
to quantum computing.
“The era of quantum computing is just beginning,
and we are looking forward to bringing that
capability to a broader audience,” said
Tony Uttley, president of Honeywell Quantum
Solutions.
Computers traditionally use bits to process
information.
But quantum computing depends on bits that
have properties of quantum physics – called
qubits.
Traditional computing bits are either “0”
or “1,” but qubits can be in both states
at the same time, a quantum property called
superposition.
Another quantum property, called entanglement,
allows for qubits to be quantum mechanically
connected to other qubits in the system.
As a result, quantum computers leverage entanglement
and superposition to solve previously impossible
computational problems.
Quantum computers will disrupt current techniques
and solve previously unapproachable problems,
creating valuable solutions for industry.
“For example, pharmaceutical companies could
accelerate the discovery of new drugs, materials
companies could discover new molecular structures,
finance companies could develop new trading
strategies, transportation companies could
optimize logistics, and companies relying
on the output of the machine and deep learning
could perform analyses that are impossible
with classical computing of today,” Tony
said.
Consider a few more industries that could
benefit:
Airlines seeking the optimal way to store
spare parts at airports.
Distribution centers wanting the best way
to maneuver robotics around a warehouse.
Oil and gas companies calculating how atoms
and molecules can be configured to protect
equipment from corrosion.
Ideal answers to these problems across industries
could be found through quantum computing.
Quantum computing will enable industries to
tackle problems they never would have attempted
to solve before.
And the quantum computing market is projected
to grow strongly through the next decade,
according to a Tractica market report.
“Wide access is important as quantum computing
makes its way into solving mainstream business
problems,” Tony said.
“Microsoft’s Azure Quantum platform provides
another path for making sure we reach a broad
audience.”
That's all for today.
Thanks for Watching.
