Australian Myki Ticketing System Finally Rolls Out on Trams and Busses

Minor Problems Predicted By Government: Few Riders Go Away Disappointed

Australian Myki Ticketing System Finally Rolls Out on Trams and Busses

In an unexpected move, Victoria's Public Transport Minister Martin Pakulaannounced last Thursday that, "Victoria’s new public transport ticketing system, Myki, will be valid for travel on Melbourne’s trams and buses from Sunday 25 July."

As you may recall, the Myki smart card ticketing system was introduced earlier this year for use across Victoria's train network but not its bus or tram networks because of unreliability issues. However, the introduction of the ticketing system on trains was marred by so many problems that the political fallout cost then Public Transport Secretary Lynne Kosky her job (she said she was resigning for family reasons). She was quickly replaced by Mr. Pakula.

Last week's announcement makes good on Minister Pakula's promise in late January that Myki would cover trains, trams and busses before the end of 2010. It also helps defuse the potential political time bomb of expanding Myki's use during the upcoming election. 

The Minister also announced the current Metcard system will be phased out in favor of the Myki system by Easter of next year.

This story in Herald Sun says that while 430,000 Myki cards have been sent out, currently only 25,000 to 30,000 are currently in use on trains. Next Easter could prove interesting.

The Minister also warned that Myki card users could expect some difficulties in using their smart cards on trams and busses, but that their problems would be addressed quickly by the Transport Ticketing Authority (TTA) and Keane Australia Micropayment Consortium (Kamco), the consortium which built the system.

"With a system of this size and complexity, issues will arise. ...There are bugs or issues that only emerge in a live environment... The TTA and Kamco are focused on fixing them as soon as they occur."

According to today's news reports, Myki users haven't had to wait long for the bugs/issues to emerge. This story in The Age says that the first day of operation in Melbourne was marked by bugs/issues involving overcharging, equipment failures, and problems with the Myki web site, which is currently still the only way to buy a Myki card, if I am not mistaken.

In other words, the current situation is similar to that which plagued Myki's introduction on trains, although the situation doesn't sound as nearly bad as what happened in January. Nor is Minister Pakula likely lose his job over whatever problems do arise.

The Myki system was supposed to be introduced in March 2007 at a cost of AU$490 million to develop and another AU$510 million to operate over ten years. It's total cost is now estimated to be AU$1.35 billion - AU$850 million for its development and $500 million for its operation through 2017.

Quantum Error Correction: Time to Make It Work

If technologists can’t perfect it, quantum computers will never be big

Quantum Error Correction: Time to Make It Work
Chad Hagen

Dates chiseled into an ancient tombstone have more in common with the data in your phone or laptop than you may realize. They both involve conventional, classical information, carried by hardware that is relatively immune to errors. The situation inside a quantum computer is far different: The information itself has its own idiosyncratic properties, and compared with standard digital microelectronics, state-of-the-art quantum-computer hardware is more than a billion trillion times as likely to suffer a fault. This tremendous susceptibility to errors is the single biggest problem holding back quantum computing from realizing its great promise.

Fortunately, an approach known as quantum error correction (QEC) can remedy this problem, at least in principle. A mature body of theory built up over the past quarter century now provides a solid theoretical foundation, and experimentalists have demonstrated dozens of proof-of-principle examples of QEC. But these experiments still have not reached the level of quality and sophistication needed to reduce the overall error rate in a system.
