In quantum computing, the question as to what physical system and which degrees of freedom within that system may be used to encode quantum bits of information—qubits, in short—is at the heart of many research projects ...
New findings debunk previous wisdom that solid-state qubits need to be super dilute in an ultra-clean material to achieve long lifetimes. Instead, cram lots of rare-earth ions into a crystal, and some will form pairs that ...
A group of researchers reports that they have achieved quantum coherence at room temperature, which is the ability of a quantum system to maintain a well-defined state over time without getting affected by surrounding disturbances
Researchers have begun to use magnets to entangle qubits, the building blocks of quantum computers. This simple technique could unlock complex capabilities.
A new study in Â鶹ÒùÔºical Review Letters illuminates the intricacies of energy exchanges within bipartite quantum systems, offering profound insights into quantum coherence, pure dephasing effects, and the potential impact ...
Quantum computers have the potential to outperform conventional computers on some tasks, including complex optimization problems. However, quantum computers are also vulnerable to noise, which can lead to computational errors.
Researchers at the University of Chicago's Pritzker School of Molecular Engineering (PME), Argonne National Laboratory, and the University of Modena and Reggio Emilia have developed a new computational tool to describe how ...
The race to develop quantum computers has really heated up over the past few years. State-of-the-art systems can now run simple algorithms using dozens of qubits—or quantum bits—which are the building blocks of quantum ...
Quantum information scientists are always on the hunt for winning combinations of materials, materials that can be manipulated at the molecular level to reliably store and transmit information. Following a recent proof-of-principle ...
For the first time, a team of Princeton physicists have been able to link together individual molecules into special states that are quantum mechanically "entangled." In these bizarre states, the molecules remain correlated ...
