Intriguing news from the world of high technology. Lockheed
Martin says it will integrate a quantum computing platform from
Canadian partner D-Wave Systems into its business, which would be
an important first. But there are skeptics. The New York
Times
reports:
Quantum computing has been a goal of researchers for more than
three decades, but it has proved remarkably difficult to achieve.
The idea has been to exploit a property of matter in a quantum
state known as superposition, which makes it possible for the basic
elements of a quantum computer, known as qubits, to hold a vast
array of values simultaneously.
There are a variety of ways scientists create the conditions
needed to achieve superposition as well as a second quantum state
known as entanglement, which are both necessary for quantum
computing. Researchers have suspended ions in magnetic fields,
trapped photons or manipulated phosphorus atoms in silicon.
The D-Wave computer that Lockheed has bought uses a different
mathematical approach than competing efforts. In the D-Wave system,
a quantum computing processor, made from a lattice of tiny
superconducting wires, is chilled close to absolute zero. It is
then programmed by loading a set of mathematical equations into the
lattice.
…
However, the company’s scientists have not yet published
scientific data showing that the system computes faster than
today’s conventional binary computers. While similar subatomic
properties are used by plants to turn sunlight into photosynthetic
energy in a few million-billionths of a second, critics of D-Wave’s
method say it is not quantum computing at all, but a form of
standard thermal behavior.
This has not stopped Lockheed Martin’s chief technical officer
from claiming an important milestone. In the Times
article, he sketches out ambitious plans, including simulation of
how radiation bursts from a solar flare or nuclear detonation would
affect satellite software.
Whereas the bits in a traditional binary computer are restricted
to one state at a time — 1 or 0, on or off — quantum computing
can simulate a bit in multiple states. The physics and engineering
of this are frankly over my head, but the point is that practical
quantum computers would be a shattering paradigm shift. They would
perform operations and crunch numbers many orders of magnitude
faster than standard processors. By that logic, they will crack
conventional encryption standards in a matter of hours by brute
force.
Indeed, cyberwarfare is a natural application for quantum
computing, but its strategic value extends well beyond, into
medical research and engineering. The technology is being pursued
by myriad universities, firms, and governments. If this
announcement by Lockheed Martin — a leading defense contractor —
and D-Wave Systems is accurate, history will remember it for
decades to come.
