To find out whether quantum computers will work properly, scientists must simulate them on a classical computer. Now a record-breaking experiment has simulated the largest quantum computer yet. [17] How fast will a quantum computer be ab... G Rajna 被引量: 0发表: 2017年 Space-Efficient Sim...
Although quantum computers may be faster than classical computers, those described above can't solve any problems that classical computers can't solve, given enough time and memory (however, those amounts might be practically infeasible). A Turing machine can simulate these quantum computers, so su...

With error rates such as these, Prof John Preskill from Caltech has argued that we are now entering the era of NISQ (Noisy Intermediate Scale Qubits) – an era of intermediate scale of quantum computers (of c. 50 to a few hundred physical qubits) that will continue to be 'noisy' i.e...
Quantum computers utilize the fundamentals of quantum mechanics to solve computational problems more efficiently than traditional computers. Gate-model quantum computers are fundamental to implement near-term quantum computer architectures and quantum devices. Here, a quantum algorithm is defined for the circ...
Quantum computers are projected to break many of the cryptographic standards that have adequately protected data for decades -- a scary thought for security professionals and organizations alike. While companies don't need tohit the panic button over quantumquite yet -- it will likely be five to...
Dr. David Reilly and his team at the Microsoft Quantum lab at the University of Sydney have developed forward-thinking hardware systems for quantum computers, which allow for communication of information between qubits and the outside world while also maintaining the stability of these qubits, a de...

Unlike current weather systems, it will be able to provide forecasts for smaller, more specific regions, assisting ...
In quantum computers addition, multiplication, and any other arithmetic op- eration have to be embedded in unitary evolution. We will stick to the Hadamard and the controlled-V (c-V ), and use them as building blocks for all other gates and eventually for quantum adders and multipliers. If...
Quantum computers are a new generation of devices that use quantum phenomena, such as superposition and entanglement, for solving computational tasks. It is believed that quantum computers18 have a great potential to outperform existing technologies in various problems19, such as simulating complex syste...
