Roles and Responsibilities of a Chemical Engineer
A chemical engineer performs a number of different tasks in the chemical industry or an organization engaged in chemical business. The tasks and responsibilities of the chemical engineer that are described in this section are based on the concept of engineering as the transformation process from science to technology. Consider the case of manufacturing a…

Defining Chemical Engineering
As with engineering, a clear and concise definition that captures the essence of chemical engineering is not readily available. The American Institute of Chemical Engineers (AIChE), the professional society of chemical engineers in the United States, defines chemical engineers as follows: Individuals who use science and mathematics, especially chemistry, biochemistry, applied mathematics, and engineering principles,…

Engineering Disciplines
The evolution of engineering is essentially a history of civilization. As early humans transitioned from a nomadic existence into settlements, there arose a need for permanent structures and systems for handling water and wastewater demands. Civil engineering developed in response to these needs, and even today one can marvel at the systems developed by engineers…

The Chemical Engineering Profession
Engineering and Engineers Engineering has been considered as the practical application of science for over two centuries. ABET, Inc., formerly the Accreditation Board of Engineering and Technology (www.abet.org), the organization that evaluates and accredits college and university programs in applied science, computing, engineering, and technology in the United States and many other countries, defines engineering…

Which quantum gates are universal?
The most common universal gate set includes single-qubit rotations and a specific two-qubit entangling gate, such as the Controlled-NOT (CNOT) gate. Single-qubit rotations can be represented by gates like the Pauli-X, Y, and Z gates, and the Hadamard gate.

Why is it called quantum?
In fact, the word “quantum” has Latin roots and means “how much.” Knowledge of quantum principles transformed our conceptualization of the atom, which consists of a nucleus surrounded by electrons. Early models depicted electrons as particles that orbited the nucleus, much like the way satellites orbit Earth.

How to understand quantum circuits?
In a quantum circuit diagram, the wires entering a quantum gate represent the qubits that are input to the quantum gate, and the wires exiting the quantum gate represent the qubits that are output from the quantum gate. The number of inputs of a quantum gate are equal to the number of outputs of a quantum…

What are gates in physics?
A logic gate is a basic building block of a digital circuit. Logic gates have inputs and outputs that are boolean values, which means that they have one of two values. These values are usually labelled true and false, or 1 and 0. True and 1 are equivalent, as are false and 0.
