Electronic cluster state entanglement concentration based on charge detection

“…[26] There are a lot of theoretical works about cluster states, such as: the optical quantum computation using cluster states, [27] generation of atomic cluster states through the cavity input-output process, [28] reduce, reuse, recycle for robust cluster-state generation in hybrid optical system, [29] and so on. [30,31] The conduction electron has become a good candidate for the realization of quantum computation, since Beenakker et al [32] broke through the obstacle of the no-go theorem [33] in 2004. An electron system has both spin degree of freedom and charge degree of freedom.…”

Efficient generation of two-dimensional cluster states in a cavity QED

“…Due to its novel application, the generation of cluster states has also been proposed in many contexts, e.g., in cavity QED with atomic qubits, [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] superconducting qubits coupled by a cavity, [18][19][20][21][22] and others. [23][24][25] It is well known that any quantum circuit can be partitioned into a sequence of one-qubit rotations and nontrivial two-qubit gates. [26] Multi-qubit gates may also play an important role in constructing quantum computational circuits, e.g., the quantum Toffoli gate is very useful in complex quantum algorithms.…”
