We propose a method of controlling the dc-SQUID (superconducting quantum interference device) system by changing the gate voltages, which controls the amplitude of the fictitious magnetic fields B-z, and the externally applied current that produces the piercing magnetic flux Phi(x) for the dc-SQUID system. We have also introduced a physical model for the dc-SQUID system. Using this physical model, one can obtain the non-adiabatic geometric phase gate for the single qubit and the non-adiabatic conditional geometric phase gate (controlled NOT gate) for the two qubits. It is shown that when the gate voltage and the externally applied current of the dc-SQUID system satisfies an appropriate constraint condition, the charge state evolution can be controlled exactly on a dynamic phase free path. The non-adiabatic evolution of the charge states is given as well.

In the paper we generalize the standard teleportation to the conclusive teleportation case which can teleportan arbitrary d-dimensional N-particle unknown state via the partially entangled quantum channel. We show that onlyif the quantum channel satisfies a constraint condition can the most general d-dimensional N-particle unknown state beperfect conclusively teleported. We also present a method for optimal conclusively teleportation of the N-particle statesand for constructing the joint POVM which can discern the quantum states on the sender's (Alice's) side. Two typicalexamples are given so that one can see how our method works.

We have proposed a quantum system with equally-distant partially-entangled alphabet states which hasthe minimal mutual overlap and the highly distinguishability, these quantum states are used as the "signal states" ofthe quantum communication. We have also constructed the positive operator-valued measure for these "signal states"and discussed their entanglement properties and measurement of cntanglement. We calculate the accessible informationfor these alphabet states and show that the accessible information is closely related to the entanglement of the "signalstates": the higher the entanglement of the "signal states", the better the accessible information of the quantum *** the accessible information reaches its maximal value when the alphabet states have their maximal entanglemcnt.

In this paper, we detail the theoretical ideas which are used to explain the mechanism of the laser controlling thegeometric quantum gates introduced in the work by Ekert et al. (Ekert A, Ericsson M, Hayden P, Inanori H, Jones JA, Oi D K L and Vedral V 2000 J. Mod. Opt. 47 2501). We have introduced a two-level Hamiltonian system, anddirected to solve this system, and then obtained the probability distribution of this two-level system. We also show therelationships between the external laser fields and the transition of the qubit in the two-qubit controlled-phase gate,and how the transition of the qubit depends on the external laser fields and the states of the controlled qubit.

BACKGROUND Ovarian tumors are common gynecological diseases in children, and the most commonly seen ovarian tumors are germ cell tumors. Robotic surgery is the new access for children ovarian *** SUMMARY From June to October 2017, 4 children with ovarian tumors were admitted and treated in the Department of Pediatric Surgery of People’s Liberation Army General Hospital. The mean age, height, and weight of these patients were 7.5(1-13) years old, 123.75(71-164) cm, and 36.8(8.5-69.5) kg, respectively. Roboticassisted resection of ovarian tumors was performed for all 4 patients. The 3-port approach was used for robotic manipulation. The surgical procedures were as follows. After creation of the pneumoperitoneum, the robotic scope was placed to explore and find the left ovarian tumor. The trocars for robotic arms 1 and 2 were placed at the sites to the lower right and left of the port of the scope. The tumor capsule in the fallopian tube was incised, and the tumor was completely stripped by an electric hook along the junction of the tumor and the capsule. The resected tumor was completely removed using an endobag. The average docking time of the robotic system was 18.5 min, the average operative time was 120 min, and the average blood loss was 20 m L. No drainage tube was placed except in one patient with a mucinous tumor of the ovary. No fever, pelvic fluid, or intestinal obstruction was reported after surgery. No antibiotics were used during the perioperative period, and the average length of hospital stay after surgery was 3 *** Robotic-assisted resection of ovarian tumors is a simple, safe, and effective surgical procedure for selected patients.

A transition edge sensor(TES)is extremely sensitive to changes in temperature,and combined with a high-Z metal of a certain thickness,it can realize high-energy resolution measurements of particles such as X-rays.X-rays with energies below 10 keV have a weak penetrating ability,hence,only gold or bismuth of a few micrometers in thickness can guarantee a quantum efficiency higher than 70%.Therefore,the entire structure of the TES X-ray detector in this energy range can be realized using a microfabrication ***,for X-rays or γ-rays from 10 keV to 200 keV,submillimeter absorber layers are required,which cannot be realized using the microfabrication *** paper first briefly introduces a set of TES X-ray detectors and their auxiliary systems,and then focuses on the introduction of the TES γ-ray detector with an absorber based on a submillimeter lead-tin alloy *** detector achieved a quantum efficiency above 70% near 100 keV and an energy resolution of approximately 161.5 eV at 59.5 keV.

通过对纤维加固超疏松和疏松饱和砂土开展不排水动三轴试验,分析了其超孔压发展规律和流动液化特性。结果表明,未加固超疏松和疏松饱和砂土具有较高的液化势,其在不排水循环荷载下均发生流动液化。离散纤维向砂土骨架提供加密效应和约束效应,从而提高其抗流动液化特性,然而,纤维的约束效应受到加载路径和试样应变发展模式的显著影响。纤维加固改变了饱和砂土残余孔压的发展规律,当纤维向砂土骨架施加较强的约束效应时,试样的残余孔压发展呈倒L型,明显不同于未加固砂土的S型发展。在双向非对称和单向循环荷载下,纤维应力贡献较大,砂土骨架的有效应力在超孔压上升100%后远大于0,加固试样的强度损失低于11%,纤维阻止了液化的发生。
