such systems behave like a single collective spin. We thus understand the emergence of complex many-body physics as dependent on ‘exceptional’, geometrically constrained structures such as the low-dimensional, regular ones found in nature. Within the space of dense graphs we identify hitherto unkno...
Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total...
Quantum engineeringFrom left to right, QUANT-NET researchers Erhan Saglamyurek, Hartmut Häffner, Inder Monga and Wenji Wu demonstrate their ion-trap quantum processor, a key subsystem in the network testbed connecting Häffner’s UC Berkeley physics lab to Berkeley Lab. QUANT-NET is a broader...
which was introduced by Planck. This discovery became the basis of all twentieth-century research in physics and has almost entirely conditioned its development ever since. Without this discovery it would not have been possible to establish a workable theory of molecules and atoms and the energy pr...
Val Zwiller, a quantum physicist at the Delft University of Technology in the Netherlands, says the two groups have made “clearly important steps” towards quantum repeaters, but notes several limitations that suggest engineering challenges still lie ahead. One of these is the low efficiency, and...
The actual security provided by a QKD system is not the theoretical unconditional security from the laws of physics (as modeled and often suggested), but rather the more limited security that can be achieved by hardware and engineering designs. The tolerance for error in cryptographic security, ...
The mission would also represent a leap in capability for nanosatellites, especially for pointing and for carrying fundamental physics experiments. It is an extremely challenging project that stacks a number of critical systems engineering fields, in particular the combination of extreme high pointing ...
models are built in time or frequency domain and can be interconnected to form quantum feedback networks. This review can be taken as a useful reference for engineers to understand the quantum physics behind, or for physicists to resolve control problems from a control engineering point of view....

The nature and frequency of errors depends on the ...
