This work-in-progress paper consists of four points which relate to the foundations and physical realization of quantum computing. The first point is that the qubit cannot be taken as the basic unit for quantum computing, because not every superposition of bit-strings of length n can be factored into a string of n-qubits. The second point is that the “No-cloning” theorem does not apply to the copying of one quantum register into another register, because the mathematical representation of this copying is (...) the identity operator, which is manifestly linear. The third point is that quantum parallelism is not destroyed only by environmental decoherence. There are two other forms of decoherence, which we call measurement decoherence and internal decoherence, that can also destroy quantum parallelism. The fourth point is that processing the contents of a quantum register “one qubit at a time” destroys entanglement. (shrink)

The FASB in its Conceptual Framework has set high principles in the ethics of standard-setting in accounting. This paper concentrates on what the FASB calls the cost/benefit constraint, i.e., the commitment to setting an accounting standard only when the benefits of the standard exceeds the costs of that standard toall stakeholders. This constraint is supposed to take precedence over other concerns, such as neutrality (freedom from bias) of account information.The major conclusion of this paper is that a conflict exists between (...) the FASB's commitment and its practice. There is no evidence that the FASB has always made a costs and benefits judgement with respect to proposed standards. In the cases when such a judgement is made, the FASB discounts social costs; therefore, it is not considering costs to all stakeholders. At the same time the FASB discounts social costs, it seems to have an undue concern for standards that do not increase the volatility of net income. The Conceptual Framework explicitly defines costs as the costs to society as a whole. (shrink)
