Many companies, including Google, Microsoft, Intel, Rigetti and IonQ, are developing quantum computers
. Universities and militaries in many countries are also investing in the research.
Exploring new technologies for quantum computers
is also a key research focus at Forschungszentrum Jlich.
For quantum computers
to perform as hoped, they will probably need millions of quantum bits, or "qubits," as well as ways to conduct operations between qubits distributed across large-scale machines and networks.
Therefore, this paper focuses first on analyzing these characteristics and afterwards on presenting the main hardware components required by a quantum computer
, its hardware structure, the most popular technologies for implementing quantum computers
, like the trapped ion technology, the one based on superconducting circuits, as well as other emerging technologies.
are the next big step in the series: Microprocessors, computers, laptops, and supercomputers.
use quantum mechanics to process information differently than classical digital computers allowing them to tackle significantly more complex calculations.
The automaker's team of IT experts have recently developed a traffic management algorithm powered by quantum computers
to precisely predict urban traffic movement.
ISARA Corp., the world's provider of agile quantum-safe security solutions, has announced the launch of ISARA Catalyst(TM) Agile Digital Certificate Technology, a first-of-its-kind technology that allows organizations and manufacturers to secure their infrastructure and connected devices from the looming threat of an encryption-breaking quantum computer
, the company said.
This includes defining the base capabilities of a quantum computer
, and tests such as a suite of algorithms upon which, if somebody's machine can solve these problems efficiently, demonstrates a capability beyond what we currently believe to be classically possible.
The main difference between currently deployed (so-called 'classic') computers and quantum computers
is that classic computers operate on bits (zero or one), while quantum computers
operate on qubits (zero, one, or a little bit of both).
"Quantum Xchange raises the bar for modern-day encryption and gives organizations a future-proof data security infrastructure to combat the looming threat of quantum computers
," said John Prisco, President and CEO of Quantum Xchange.
