Quantum Sensor Technology and its Application

By

 

Quantum sensors are new and promising technology developing rapidly along with the quantum computing engineering because it provides ample insight into the environment of qubits. Quantum sensors depend on the mysterious behavior of subatomic particles called quantum states, where the classical Newtonian physics do not exist and have prominent real world application of quantum mechanics. Quantum sensor extends operating range, dynamic range, capability and sensitivity of the sensors used in the different application. Now a day, more mature sensor implementation is available for different applications.

In recent years quantum sensors are used to measure various physical quantities such as temperature, pressure, electric and magnetic fields and frequency of revolutions etc. by using quantum object. A quantum object is designed by using quantum states properties such as quantized energy level, quantum state squeezing, quantum coherence or entanglement to improve sensitivity of the measuring instruments. Prominent application of quantum sensors is the development of atomic clock, Quantum Compass, diamond lights, high resolution spectroscopy, atomic magnetometers etc.

Quantum sensors may also be used to predict the detailed mapping of the minor traces of explosives, mapping of the underground environment, autonomous vehicles, brain-machine interaction, and improved imaging technologies, detection of minor.

Recently, various militaries forces researches on the potential use of quantum sensor technology in the stealth detection application, so that detection of radar signature of a fighter jet is not possible. A scientist in the US research lab developed Rydberg Atoms, which is sensitive to the wide range of frequency without absorbing to energy from the radiating fields. It means, we are able to detect an object without our opponent knowledge.

Teacher As: Critical Pedagogue

By
Education is not only a process of cognitive development. It is a process of overall development of the child. The whole teaching learning process consist with three important components i.e student, teacher and curriculum. In the process of curriculum construction, evaluation and feedbacks are an important aspect to redesign the curriculum. Evaluation cannot be made on the basis of academic achievement of the students. Teacher should play an important role in the construction of curriculum as well as transaction of curriculum. Thus there is a need that teacher should take initiative to evaluate the whole education system as a Critical pedagogue. It is an ability to evaluate our teaching and the practices prevailing in existing education system critically in relation to methods and practices adopted by the teacher to teach concern pedagogical subjects. Ira Shor defines “ Critical pedagogy is habits of thought, reading, writing and speaking which go beneath surface meaning, first impr...

ROLE CONFLICT PROBLEM AMONG WORKING WOMEN

By
Women of India have marked their significant presence in the world in various fields. They have been given the status of power and prestige in India.    Indian women has got much more significance in today’s developing times.

Not only has She taken up courageous roles in society, her own individuality as a ‘woman’ has now got an improvised meaning. The world has changed for females in India now. The daughters are pursuing successful ambitions in the male dominated corporate scenario and mothers are taking up flextime jobs to showcase their exceptional managerial talent. Today, our women have stepped out to become bread earners of the family. Although the trend is yet developing in India, The IT-BPO sector is becoming a female dominated industry in India with a significant number of capable a...

As per section 17 of depository Act the rights and obligations of the depositories, participants and the issuers whose securities are dealt with by a depository shall be specified by the regulations. Under the Depository Act, 1996 depository means a company formed and registered under the Companies Act, 1956, and which has been granted a certificate of registration by SEBI under sub-section (1A) of Section 12 of the Securities and Exchange Board of India Act, 1992 ). (Section 2(1) (e)) Work of Depository- The word ‘depositary’ is defined as “the party of the institution (company) receiving a deposit. A depository holds securities (like shares, debentures, bonds, Government Securities, units etc.) of investors in electronic form. Besides holding securities, a depository also provides services related to transactions in securities. It acts as a trustee of the owner since the securities are entrusted with him in trust. He is also the agent of the owner of the securities. Thus...
