THE MECHANICAL VACUUM PUMP
We will conduct our experiments in the range of 10 Torr to 10 mTorr, which is easy to achieve using a low-cost, mechanical vacuum pump. Very good results have been obtained by amateur experimenters and educators using vacuum pumps made for servicing air conditioning and refrigeration units. These vacuum pumps are not part of the…

THE NEED FOR VACUUM
The experiments in this chapter will deal with the production and detection of subatomic particles, such as electrons and nuclei. As these interact with matter, including air, many of the experiments need to be carried out inside glass tubes out of which the air has been pumped. The normal atmospheric pressure at sea level is…

What is the unit of quantum information?
Just like a binary bit is the basic unit of information in classical (or traditional) computing, a qubit (or quantum bit) is the basic unit of information in quantum computing.

What is the principle of quantum?
Quantum principles refer to the fundamental laws that govern the behaviour of particles at the quantum level. For instance, wave-particle duality of matter, uncertainty principle, and superposition.

EXPERIMENTS AND QUESTIONS
Solder two temporary wires to the two electrodes of the lightbulb that you will use for the blackbody radiation experiments. Measure and record the room-temperature resistance (Ro) of the tungsten filament using a precision multimeter. Unsolder the wires and place the lightbulb on its base. Connect the lamp to the variable power supply and two…

What is the principle of quantum information and quantum computing?
Ans. Quantum computing uses principles of quantum physics such as superposition and entanglement to perform computations. It encodes information in quantum bits or qubits. This allows exponentially large information processing capacity compared to classical bits in regular computers.

What are the main features of quantum?
Its two most important features have survived in present-day quantum mechanics. They are (1) the existence of stationary, nonradiating states and (2) the relationship of radiation frequency to the energy difference between the initial and final states in a transition.

WHERE DOES THIS LEAVE US?
Einstein made very convincing arguments for the particle nature of light. However, as we saw in chapter 1, Young’s experiments with the interference of light, and Maxwell’s explanations about the polarization of electromagnetic waves had already destroyed Newton’s view of light as a stream of particles. So where does this leave us? We will return…

LISTENING TO INDIVIDUAL PHOTONS
All of the experimental demonstrations above have looked at the particle nature of light using billions of photons. Wouldn’t it be more convincing if we could observe a single particle of light at a time? The setup of Figure 33 gives us an opportunity to detect individual photons. The detector is the PMT probe that we just…
